Tab drag-n-drop completely broken

Reported by teo8...@gmail.com, Jul 4 2017

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.86 Safari/537.36

Steps to reproduce the problem:
This is a huge regression, not sure whether entirely in Chrome or partly or totally in Ubuntu's window manager (is it Unity?).

I'm under the impression that this doesn't always happen, but when it starts happening it becomes 100% systematic (rendering the tabs completely unusable) until, at least, the next reboot.

1. Open several tabs in a window
2. Press the mouse button over a tag, don't release it, and start dragging. Don't release the mouse button
3. Drag the tab away, as if you were to drop it into a new window, but don't.
4. Drag it back into the tabs bar of the original window, in order to drop it into the original window
5. release the mouse button

What is the expected behavior?
At step 4, the new window that had temporarily been created while dragging should be destroyed and the tab you are dragging should go back to the original window. At step 5 the tab should be definitely  left into the original window

What went wrong?
Once this has started happening, it will NEVER behave as expected. Instead, it will exhibit one of the following nonsense behavior (repeat several times to observe all of them):

I. You just can't do step 4, that is, you can't drag the tab back to the original window. The new temporary window will stick somewhere below where you are trying to drag it, and you will only be able to drop it into a new window.

II. So now you click again on the tab that you have moved into a new window, and drag it back into the original window.
Now this time, when dragging it to the tabs area, it will for a fraction of a second go back to a tab (that you still have to drop), but immediately it will go back to a new window even if you don't drag it away.

Again, you won't be able to drag it back to the original window in ANY way.

III. When you drop it outside the original window in order to definitely create the new window, it will automatically maximize to the whole screen, regardless of where you drop it.

Did this work before? Yes I don't know, pretty recently

Unable to reproduce the issue on Ubuntu 14.04 and Win-10 using latest chrome stable #59.0.3071.115 and latest dev #61.0.3141.7.

Attached a screen cast for reference.

Following are the steps followed to reproduce the issue.
------------
1. Opened 15 tabs in a window.
2. Dragged a tab out of the window.
3. Tried dropping the tab into the original window.
4. Observed that tab was dropped into the original window without any issues.

teo8976@ - Could you please verify the screen cast and please let us know if anything missed from our side. Also please check this issue in latest chrome stable #59.0.3071.115 by creating a new profile without any apps and extensions and please let us know if the issue still persist or not.

Thanks...!!

The screencast is fine. It's quite possible that you can't reproduce.

I can confirm this:
> I'm under the impression that this doesn't always happen

It does happen randomly. I don't know how to trigger it at will. When it starts happening, however, it keeps happening systematically, and even restarting Chrome doesn't fix it (at least not always). Not sure if there's anything that fixes the issue (meaning stops it from keeping happening) besides reboot.

It seems quite likely that it is linux-specific.

Removing the Needs-Bisect label as this issue seems to be inconsistent.

This may depend upon the window manager you are using.

Comment 7 by teo8...@gmail.com, Jul 11 2017

Yep, it may. I'm using the one that comes by default with Ubuntu 16.04, I think it's Unity?

@teo8976-- Could you please let us know if you can still able to reproduce the issue on latest stable M60 #60.0.3112.78 using fresh chrome profile without any extensions and flags enabled.

Thanks!

I'm just observing this again. As usual, now that it has randomly appeared it's systematic. Restarting Chrome doesn't fix it (rebooting probably will).

I can't in any way drag a tab into an existing window.

We were unable to reproduce this bug . If this bug still reproduces for you, 
please reopen or file a new issue. 

Thanks..!!

Observing the issue again.

For fuck's sake, reopen and fix it!
I have already commented that this shows up rarely and randomly, so please don't close it just because you are unable to reproduce at will!

OP, can you record a screencast of the issue?
It could take me ages, because usually when it happens I don't have the time to waste to record a screencast, and then on reboot the issue disappears and it can be ages until it reappears randomly.
