+Subject: [PATCH] Fix informing the underlying widget when leaving
+ SplitterProxy
+
+While the SplitterProxy is active, it intercepts all relevant events, so that
+the underlying widget still thinks it's in the same "on splitter" state. When
+the SplitterProxy is left, the underlying widget is sent a HoverLeave/HoverMove
+event to make it aware of the new current cursor position. Without this, it
+doesn't know that it's not supposed to be in the "on splitter" state, and when
+it regains focus it just re-activates the SplitterProxy at the current cursor
+position.
+
+This was broken by accident in d201a1f187 ("Fix SplitterProxy not clearing
+when above another QSplitterHandle"), which moved the hide() call past the
+call to QCoreApplication::sendEvent. Previously that made isVisible() false,
+which also prevented the interception of the HoverLeave/HoverMove events.
