FFM: Hovered window doesn't active on space change

[tgl@…]

When I use control-arrow-key to switch to another Space, if the cursor is within an X11 window and focus-follows-mouse is on, I'd expect that window to acquire focus. It doesn't though. Moving the mouse even slightly will cause it to acquire focus, but IMHO I shouldn't have to do that.

Some experimentation says that the behavior is the same when using the F8 view to switch spaces, though you have to be quite careful when clicking in the view not to move the mouse, else that motion will allow focus to be acquired.

Note: this is with 2.2.1 but the "version" menu hasn't yet got an entry for that.

Further note --- it seems that after switching with control-arrow-key, not only does the window now under the mouse not have keyboard focus, but the window that was under the mouse in the previous space DOES still have focus and will receive keyboard events. That's just unalloyed dangerous, and might justify treating this as priority higher than "minor". Ticket #98 seems to be reporting something related.

We might be able to do this my forcing a new MouseMotion event on space-change.
