Toolbar Positioning controls don't seem to work when set relative to monitor

When setting position relative “to monitor”, the control only seems to respect ‘From Left’ and ‘From Top’. Changing it to ‘From Right’ and/or ‘From Bottom’ has no effect.

This control does work if setting the position relative to the window, but not if setting relative to monitor.

I can provide more details, screenshots, and such, if needed.
