Electric window

No. Not tested at MOT nor is mirror heating. You’d have been lucky to find the handle still in place in the past since it would have been pinched for the driver’s side. The only criteria for a side window MOT failure would be:

“So insecure that it is likely to fall out or damaged to the extent that it presents a danger to occupants or to other road users” or " With damage or obstruction, which impairs the driver’s view of a mandatory mirror".
