fix(OverflowMenu): add stopPropagation call to handleClick method

[rzhekova]

Closes #9744

To fix the issue I added an event.stopPropagation() call to the handleClick method in OverflowMenu which stops it from happening. The event method appears to prevent propagation and bubbling up of events which is probably what happens with the click in OverflowMenu.

I have also added a unit test.

Thanks!
