Fix infloop in bidi.c
* src/bidi.c (bidi_set_paragraph_end): Reset the isolate_level to
zero. Whenever stack_idx is reset to zero, the isolate_level must
also be reset, since there cannot be any isolate status outside of
embeddings. Failure to reset isolate_level will cause us infloop
when we see a PDI. Reported by Matt Beshara <m@mfa.pw>.
