I once had difficulty parking because of the way the car in front of me had parked and I couldn't get all of my car in the space.
Fortunately, there was a warden close by,( You can usually find them hovering around the disabled bays) so I asked him if he was going to give me a ticket and he said, No.
As long as my 2 front wheels are in the space, it's ok.
Looks like that lady didn't have her front wheels in the space, but if she isn't causing an obstruction, I don't think she should have to pay a fine.
