When a TextInput is in a Popup over an item with a HoverHandler in it then the event can end up passing through to underlying item which can trigger unexpected behavior. In the example, if you try to press and move the mouse in the middle of the text (where there is whitespace) it will suddendly close the popup and start moving the tableview underneath (this is because the popup is closed when the table starts moving).

The first time the popup is there it does not happen, so in the example click outside the table to make it go away then double click on any of the cells to make it reappear. Then you can try to press and move inside the text (it might take a couple of goes to trigger it) and then it will pass through to the hoverhandler. If the hoverhandler is not there or is disabled then this never happens.
