Capturing items no longer work, cancels out of menu

[codemann8]

I noticed an issue on this latest push/fix, badge icons aren't placing when you select an item from a capture grid. Or likely a problem that clicking on the capture grid item is canceling out of the menu without filling the capture.

Fixed in PR #43. The map popup light-dismiss handler was closing the location details popup when clicking inside child popups (like the capture grid) because Avalonia renders popup content on a disconnected overlay layer. The handler now correctly detects clicks inside popup overlays and leaves them alone.
