[BUG] Printing starts without filament

[gnulf2004]

Printer type - [e.g. MK3S, MK3, MK2.5S, MK2.5, MK2S, MK2]
MK3S+

Printer firmware version - [e.g. 3.8.1, 3.8.1-RC1, ...]
3.14.0

Describe the bug
Since firmware 3.13.2 my MK3S+ tries to start printing even when there is no filament loaded. With previous firmware versions the printer stopped after the bed level test and asked to load filament, but now the printer ignores the missing filament and just starts printing. I reported this issue back in November 2023 to Prusa support, but nothing happened :-(

To Reproduce
Unload any filament and start printing from SD card or USB. After bed level test, printer will start printing without filament.

Expected behavior
The firmware should check the filament sensor after bed level test to make sure that filament is loaded. If filament is missing, the user should be asked to load filament.
