Dismissing dialogs sometimes leaves menu selected

[bewihelm@…]

When using the keyboard, opening a dialog like Find & Replace and then dismissing works fine if the Edit
menu has never been opened. But if it has been opened, then opening Find & Replace and dismissing
results in the Edit menu being highlighted (but not dropped down). The only way to get rid of this
highlighting is to use the mouse to click open a menu. (This behavior does not happen when opening
document settings with the mouse.)

This is an issue for any dialog in the first level of a menu (but not for drop-down sheets such as File >
Open, and not for the LyX menu), including File > Print, Edit > Find & Replace, Edit > Paragraph settings,
etc.

Is it still valid?

[bewihelm@…]

Yes. (Might #3165 be related?)

What's the status of this regression bug?

[bewihelm@…]

This looks to be fixed. I'm marking it that way.
