Popup windows open on different monitor in dualmonitor setups

In dual monitor setups, with PD on secondary monitor, popup windows open on primary monitor.

Not sure if this is packaging issue or upstream issue.

No files, tests, or entry points are identified in the issue. First reproduce the behavior with Purr Data on the secondary monitor in a dual-monitor setup, then determine whether the popup placement comes from packaging or upstream behavior. Done when popup windows open on the monitor containing Purr Data, or the upstream source of the issue is clearly identified.
