[Bug 39264] wininet may try to decrypt one more ssl message than needed

Yes, I should have mentioned that. Sorry.
In my opinion if we already read the data, there is no need to try decrypt
another message, but you are the expert.
The other way is to check on next call to read_ssl_chunk BEFORE the assert if
we already have all the data. Or change the assert to be <= and after that make
the check and break.
I'll leave the best course of action to your expertise, but I hope you
understand why this is a problem.
