Well, you should bring up the issue on the Scintilla mailing list, but
I wouldn't be too hopeful since technically the parser is doing the
right thing parsing everything as a string and so losing the folds.

Note that the same thing happens with multiline comments in C/C++,
when you open the comment everything after loses the fold points and
is unfolded. At least until a close comment is encountered.
