Could anyone from the dev team please look into this issue.

Thanks in advance..!!

yhanada@: Could this be related to https://chromium-review.googlesource.com/c/530726/.

Thank you for reporting.

I changed the default visibility of the close button on pop-ups to address  crbug.com/726812 .
Is there any other problem to move the button back to the lower-right corner as before M-59?

The "x" button is seen overlapped with text in screenshot. You can either fix that or can revert back to M59 design.

sgabriel@: What would you suggest to fix this issue? Is it ok to reduce the width of the title not to be covered by the button?

this solution sounds good. try to put something like 8px padding between title label and X button container.

Thank you for reviewing!
A close button a settings button can be overlapping on text of a notification without the fix. This makes it harder for users to read content of a notification.
The change is in 62.0.3188.0. We should watch for one or two days. I'm sorry for requesting merge too early.

The change fixed only the overlapping issue.
Visibility of a close button and a settings button is working as intended. Please see  crbug.com/726812 .

Thanks!

Thank you  yhanada@.Per comment #14, this issue doesn't seem to be fixed on Canary version 62.0.3188.0. Could you please double check?

 

As discussed in  crbug.com/726812 , always showing up close button and settings button is the intended behavior.

The CL fixes the problem that these buttons overlap text of a notification.

I found that there is another minor issue in layouting views in notificaiton, so I'll try to fix the all issues completely in M-62.
I'm withdrawing the merge request. Sorry for the confusion.

Rejecting merge to M61 based on comment #17.

The issue I mentioned in #17 is tracked in  crbug.com/785589 .
