hyperlink tooltip doesn't update if invalid utf8
@egmontkob
Submitted by Egmont Koblinger Link to original bug (#786814)
Description
Have two hyperlinks right below each other, one of them having an invalid UTF-8 target. E.g. with the patched "ls" command and an invalid UTF-8 filename.
Mouseover the valid UTF-8 one, wait until the tooltip is shown. Then move the mouse over the invalid one.
Actual: Tooltip text remains the same (the previous filename).
Expected: Show U+FFFD replacement characters, or at the very least an empty popup (as done now if you mouseover here from a non-hyperlinked cell) or perhaps nothing at all, but definitely not some other cell's target.
Version: git master
