Changes

Description

• Focused the maximizeToggle button even when using a shortcut, so that it stays in the screen view.

Clarifications

• When checking out the code, I figured out the exact same function call happens when clicking and pressing a key to minimize the gallery. Therefore the difference in behaviour must be related to "something else" that happens when clicking that does not happen when pressing the shortcut key. One of those things is that the user focus is set to the maximize toggle. I tried focusing the maximize toggle and this solved the bug. This change is pretty straightforward and doesn't impact much the user experience except for having correct scrolling.

Screenshots & Video

Here is a demo of how the gallery minimizing behaves with the changes.

Executed Tests

Manual tests only, see video above.
Automatic tests didn't catch this behaviour, and the changes don't impact the DOM in any way, so I am almost certain that no automatic test will be broken by this change.

Expected merging strategy

• Prefers squash: Yes
• Backport on branches:
  • 16.10.X (rather safe bugfix)
