wayland: Don't send invalid anchor rectangles

Browse Source 
When we send an anchor rectangle with a width or
height of 0, mutter reponds with "Invalid anchor
rectangle size". So, don't do that.

This was seen as sudden disappearance of gtk4-demo
when you click the fishbowl benchmark all the way
through to the menubuttons.
