Fixes #5616: toolbar tooltips pointing wrong way in mail demo
Fixes #5616: toolbar tooltips pointing wrong way in mail demo

Problem occurred when tooltip didn't fit in any of the positions but it still picked the best spot (in this case, best match was tooltip to the right of the button with bottom borders aligned, but the tooltip was too tall and overflowed the top of the viewport by a pixel).

Still having an issue with the button "get mail" ComboButton getting cutoff, and with tooltips not disappearing.
