the accidential switch from status to jobqueue tab is fixed but:
after cancelling the first print job, and starting a new one, the panel will still not switch to the status tab. it stays on the files tab.

reproduction steps:

1. enforce fresh rendering of panel
2. start a print from files tab
3. observe the panel correctly switching to the status tab
4. pause -> cancel -> clear print
5. observe the panel correctly switching to the files tab
6. start another print from files tab
7. observe the panel INCORRECTLY staying at the files tab - expected to switch to status tab!
