(security) Nheko freezes Ungoogled Chromium, then upon exit brings U/C down with it!

This seems quit serious because there is a security issue when one app can interfere with another.

If Ungoogled Chromium is running when Nheko launches, U/C instantly freezes. No i/o is possible with U/C. Then when Nheko is quit, U/C goes down with it.
