Chrome Version       : 69.0.3497.92 (Official Build) (64-bit)
URLs (if applicable) : 
OS version               : 10.13.6
Behavior in Safari (if applicable): Tab remains floating until user stops holding it; it can be placed back on window.
Behavior in Firefox (if applicable):

What steps will reproduce the problem?
(1) Open new Chrome instance
(2) Make it full screen (green button, so that it has its own window)
(3) Add one or more tabs
(4) Detach any tab from browser, without letting go of it (keep 'holding' it)
(5) Attempt to place tab back into the Chrome window it was initially in

What is the expected result?
User should be able to 'hold' detached tab within the same window without the tab immediately going into its own window. This used to be the result before the latest UI update.

What happens instead?
Detached tab immediately goes to new window, and it's annoying/time consuming to try to put the tab back where it was. This happens a lot when I'm trying to reorganize tabs and accidentally detach a tab.
