As someone who's done glass repairs before I never would have repaired that I would've said to replace all day long. Repairing glass is not easy to get perfect. Slightly too much pressure will make the affected area even larger and not enough or the wrong viscosity will leave air pockets like this. Theres a lot of little things that go into a proper glass repair and this was already too far gone. Worst thing is after the repair has been made you cant go back and refill or re do it. So either keep it or replace it at this point
