I can replicate this bug on a real RAMPS and REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

Its apparently been broken for some time

I did a git bisect on this and identified commit 5523c12 as the cause of the reboot
ie #26381

NOTE: issue does not show up in the sim, it may be AVR hardware specific
Also works without rebooting on Creality V4 32bit controller
