Emilio Cobos Álvarez 3d6d2d9586 Bug 1440682: Make the XUL tooltip stuff saner. r=enn
We never removed the event listeners (the code was there, lol, but the function
that was supposed to call into the tooltip listener returned
NS_ERROR_NOT_IMPLEMENTED instead).

Furthermore, we added an event listener each time we reframed an element, which
is insane. Basically, each time an element with tooltip / tooltiptext gets its
frame tree reconstructed, we add the even listener, again, and we never free it.

Xidorn pointed out that this is not such a huge deal because we deduplicate
event listeners per spec, but still...

Move the code from the RestyleManager and the frame constructor to AfterSetAttr
/ BindToTree / UnbindFromTree in nsXULElement to hopefully make this saner.
