Pause from devtools debugger is not triggered until I click on the app

I am running dart devtools on Mac using `pub global run devtools`, and connecting to an app that runs on a linux machine using ddr.

If I hit "pause" in the debugger, nothing happens until I click on the window where the app is running, in which case the debugger pauses correctly.

Is it possible to trigger the app to stop from the debugger automatically?

The report concerns Dart DevTools launched with `pub global run devtools` and an app connected through ddr across Mac and Linux. Reproduce the debugger pause flow in that setup, then trace the pause request and verify that the app stops without a window click. Done means the remote app pauses automatically when Pause is selected.
