Deliver context menu event with correct coordinates to widgets in popups

If a popup is open, Qt delivers events to the popup child under the
mouse, so we need to correctly translate the local position of the
context menu event to that child's coordate system.

This is already done correctly for regular mouse events, so use the same
logic here.
