Chrome Version: 70.0.3538.67 (Official Build) (64-bit)
OS: MacOS 10.13.6 

What steps will reproduce the problem?
(1) Have two windows with 2 tabs each. Have one window be mostly behind the other (notably the foreground window should block the tabs of the background window. The background window should pop out from the bottom
(2) Drag a tab from the foreground window to the background window (so to the exposed bottom part)
(3) Notice that the background window doesn't go to the foreground

What is the expected result?
I think it used to come to the foreground to make it easier to drag and drop

What happens instead?
The background window doesn't come to the foreground making it harder to drag and drop tabs between windows.
