Public bug reported:

mir_demo_server(_minimal) version 0.13 and later: Window
movement/resizing stops responding when the cursor leaves the surface.

If you move or resize a surface with Alt+(button1/button3) then it's
very easy to get the shell into a state where the window stops
responding to movement/resizing and even becomes unrecoverable.

Essentially the problem is the shell is only looking at the current
cursor position and doesn't do anything if it's outside of the surface.
This is frustrating as waiving the mouse around a bit it's very easy to
reach this situation.

It should be looking at the gesture as a whole and only doing position
checking at the start of the move/resize gesture (ie. mouse button
down). Thereafter the gesture should be continuous until the button is
released, regardless of whether the cursor is still inside the
surface/titlebar. You will find this is how all real desktops work, and
mir_proving_server tries to too. Surfaces should always "own" input
regardless of cursor position, just so long as the gesture (mouse down)
began on that surface.

The "unrecoverable" bit: This happens if you resize a surface too
small/thin and it becomes impossible to resize it bigger again.
