Bug - Color Change/Load Filament Not Working Properly

I'm not sure where to submit these bugs, but need to bring this issue up

My issue is when I load filament but if it fails to get caught by the gears and to push through the tube to the extruder end on the initial run, there's no way to repeat that action unless I restart the loading process. When you select the option if the "Color is correct?" with "No", it will push the filament, stop, but no longer ask the question again, "completing" the load filament routine. You would have to restart the Load Filament routine again. There seems to be no manual way to tell the printer to keep stepping the motors to push the filament till it reaches the extruder based on your own judgement. This is workable as long as you did this before starting a print.

I found out the hard way when a print was paused due to filament run out. I loaded the new filament, but failed to have the filament load into the gears and missed the "initial load" that covers the distance to the extruder tube. When I pressed "No", I saw the filament started to exit out of the loading gear. But because of the bug above, the load filament routine completed and the print resumed, thus printing without any filament. I paused the printer trying to think of how to redo the filament load. I tried the "Change Color Filament" option during the print, but the option didn't do anything. Eventually I got an E1 error and the parts weren't heating up, so the print was considered a failed print and I restarted the printer. I believe it was trying to reach the Change Color Filament state but failed somewhere.

It is currently heating up properly and I loaded the filament again, but as of now, you have "one shot" to load the filament correctly midprint, else risking printing layers without any filament.

This happened to me on initial 4.0.0 firmware and the updated 4.0.1 firmware.

Probably best to create an issue on github: https://github.com/prusa3d/Prusa-Firmware-Buddy
