Tank with beat up corner. Trash, salvageable or fine as it is?

[Munin]

I rescued this 50gallon tank from a garage. On the first inspection I thought it looked good(silicone is fine and it's feels very solid overall) and I have tried to waterfill it for 2 days, it holds water just fine so far.
Anyway upon further inspection I realised that one corner is quite damaged and I even had a small piece of glass loosen from it when I tried to inspect. My main concern is simply if it will hold up over time or not, if you believe it's in bad shape is there any repair/safety measures I could possibly do without replacing the panel? (wouldn't be worth it for me personally)

Any advice and thoughts are welcome.

Yeah, that looks pretty bad. I've resealed many tanks, but unless you put some metal corner molding on it with plenty of silicone 1, I don't think I'd personally trust it
