Open Firefox and switch to the other activity OBSERVED RESULT The Firefox window is present on both activities EXPECTED RESULT It should be present only in the activity in which it was launched SOFTWARE/OS VERSIONS Operating System: Kubuntu 19.10 KDE Plasma Version: 5.18.0 KDE Frameworks Version: 5.67.0 Qt Version: 5.12.4 Kernel Version: 5.3.0-29-generic OS Type: 64-bit Processors: 2 × Intel® Core™2 Duo CPU P8600 @ 2.40GHz Memory: 3,7 GiB
