Subject: [PATCH 2/2] subparse: Skip after the end of a valid closing tag
 instead of only skipping `<`

This is a small optimization and avoids restarting the next parsing
iteration on already accepted data.

On its own it would also fix ZDI-CAN-20968 (see previous commit) but the
previous commit independently is also a valid fix for it.
