Wt

Affected: WApplication::focusedWidget and WApplication::focusChanged_ of Wt 4.13.0
WApplication::focusedWidget often returns nullptr although a WFormWidget has the focus.
There seems to be a race condition in the sequence of "lost/got focus" events.
It does not matter how the widgets are focused (click, Tab, setFocus()).

In addition, I wonder why WApplication::focusChanged_ is emitted on every key event.

Slightly related to Improvements #14480: Handle focus for all widgets.
