Unsaved list is closed without warning

[protux]

What is expected

If there is an open list with unsaved actions I expect to get a warning that I'm about to close a list with unsused actions and that I'm about to lose the progress. Then the user should be able to abort or continue.

What happens actually

The list will be closed without any alert or warning.

How to reproduce

To reproduce open a GPX file of your choice, delete a cache from that list and click the upper right "x" to close the list (not the window).
