Popup does not clear after de-hovering

[Popolechien]

Use case: I generated a list, then removed some items. When the mouse hovers on the +/- symbol then the file name appears. In this case I removed bangla content and added english, but the mousehover text box did not clear properly (even when clicking randomly around the window).

As a quickfix, I would probably no show these text boxes in the first place.
