Possible bug during upgrade

I just upgraded my flipper to 0.71.1 via bluetooth from the android app. During the transfer I inserted a power cable into the flipper and transfer continued just fine.
After that nothing seemed to happen. I pressed the down button and the screen lit up and showed “updating… manifest updating” or something like that. It was stuck there and nothing happened. I found this a bit strange.
By coincidence I pulled out the power cable and now suddenly the screen updated and the fw update was almost done (like 80% done) and the text actively changed as the update finished.

This seems to be a bug that the power cable blocks the screen from updating during fw upgrade
