To fix the mouse hover still appearing you need to catch when the tooltip frame becomes visible.

Also Text fields don't accept text keys. Either use a exact string match w/ escaped xml or property bind.  Tooltip fields can use text keys (see below). This also allows for localization to be used as well.
