Describe the bug

I have a print that isn't printing well with the default PrusaSlicer profile for Prusament PETG. The extruder quickly clicks and stops the print, complaining of stuck filament. While it stands there saying it's clogged, it will happily ooze filament.

To salvage the print, I did as it asked and reloaded (the same) filament, then I paused the print as fast as I could before it could click again, and lowered the speed setting in the Tune menu to 50%. When I resumed printing it continued printing just as fast as it had before, and the extruder clicked again. After reloading, resuming, quickly pausing and going back into the Tune menu, I saw the speed was back up to 100%. I repeated this once more to make sure I didn't do it wrong, with the same results.

I had to use the Prusa Connect interface to lower the speed.

How to reproduce

1. Print at 100% speed
2. Pause the print
3. Go into Tune and lower the speed setting
4. Resume print

Expected behavior

5. Printer honors the lower speed setting and doesn't revert it back to 100% on print resume
