What happened?

Because of the strange way that tree-sitter-php structures its tree, I use an unusual method to determine which ranges of a .php file are HTML and which are PHP. It tries to match balanced pairs of <?php (and equivalent) and ?>.

But I did something silly: when it finds an unbalanced token, it throws an exception! This exception goes uncaught and ends up preventing any editing attempts by the user.

Instead, it should be more tolerant of errors, and do something logical, even if it's not going to be correct. (The code is syntactically invalid in this scenario, so there is no such thing as “correct”; favor the solution that keeps the editor running.)
