There's #8285 which is pretty small (lots of logging stuff for removal
before a final PR); assuming nothing better comes along...
Look at `HookFileMenu` and the early return in `propertyChange()` for the PR.
Basic problem is that `Alt-F` handling, when starting in a detached window,
intermediately transfers focus to a `TopComponent`. See the "With Activation
(behavior after #4603)" log data below; notice that the
`tc.requestActivation()` processing happens after the `Alt-F` handling which
leaves the focus in the wrong spot.
I don't particularly like this solution. But can't think of anything better,
possibly a custom focus manager (ouch).
