@nosze @size and gcode preview

Did something change with the @nosize @size? Or maybe it's my newly added the MMU2S to my MK2.5S?

The gcode preview appears to still be showing the purge line which is zooming out the preview.

Start gcode:

;@nosize
M115 U3.7.2 ; tell printer latest fw version
M92 E141.26
G90 ; use absolute coordinates
M83 ; extruder relative mode
M104 S160 ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S160 ; wait for extruder temp
G28 W ; home all without mesh bed level
M860 S35 ; Wait for Pinda to reach 35C before leveling
G80 ; mesh bed leveling
M109 S[first_layer_temperature] ; wait for extruder temp
G21 ; set units to millimeters

; Send the filament type to the MMU2.0 unit.
; E stands for extruder number, F stands for filament type (0: default; 1:flex; 2: PVA)
M403 E0 F{"" + ((filament_type[0]=="FLEX") ? 1 : ((filament_type[0]=="PVA") ? 2 : 0))}
M403 E1 F{"" + ((filament_type[1]=="FLEX") ? 1 : ((filament_type[1]=="PVA") ? 2 : 0))}

M403 E4 F{"" + ((filament_type[4]=="FLEX") ? 1 : ((filament_type[4]=="PVA") ? 2 : 0))}
