Thanks for confirming this for me. I wanted to make sure whether this is a known issue or a new one. This lets me log them properly so both could have gotten fixed, and to also keep the public portal neat and tidy.
I tried reproducing an issue when I am sure the mouse didn't go over Item 2, but I was unable to. I am attaching a short video from my test so you can confirm if I am missing something. Could you also clarify what you mean with "select with the mouse" - does this require a click, a click+hold+drag to create selection, or only hovering the menu item?
