Description

The text-editor window does not seem to lose focus on alt-tabbing in Fedora 26, Gnome 3.24. This seems to be a regression introduced in Atom 1.19.0 (reproducible in 1.19.4). This was once fixed in #12591 but the issue reappeared with the newest Atom version.

Steps to Reproduce

1. Have a document open in Atom, notice the position of the scroll bar
2. Alt+Tab to a window over Atom
3. Scroll down a lot
4. Alt+Tab back to Atom
5. Scroll down

Expected behavior:
The editor window scrolls down a bit

Actual behavior:
The editor windows scrolls by the sum of the scroll amounts in step 3. + 5.

Reproduces how often:
100%
