It's stretching it and TBH, De Minimis may be the better way to go but arguably, you did not stop for stationary vehicles.
You were creeping across, intending to carry on straight, behind the grey vehicle so as to clear the box.
But the black vehicle to your left did not give way so forced you to stop...and was not a stationary vehicle at that point.
The point being that you did not have to stop due to stationary vehicles but due to a moving one.
TBH, I suspect an adjudicator would disregard or reason that the queue you were trying to join was stationary and forcing your way in, relying on the goodwill of others counted.
But council could muck up their answer or ignore?
