Thanks for testing this on Mac. I always need to ask someone in order to test the changes, so really appreciating that.

The fix prevents the dispatcher from jamming when the event loop it thought was leaving enters a new loop instead. Over in the Mac Glass code I also added a comment with a few more details on what's going on.

I tested your code and it looks good! So this seems to be the better approach here. While mine works for Windows and maybe Linux, it does not for Mac as you also specified.

The return value of the native nested event loops are still not needed, so we can still think about keeping this change, but we should probably revert the EventLoop changes and take your fix instead.
