syntax-ppss doesn't work correctly, as you know full well, having
snipped the bug number (#22983) for the breakage from what you've cited.
That bug has been open for almost a year, and there was a whole thread
on emacs-devel about asking for it to be fixed back last summer.  I've
asked several times since then for it to be fixed, to no avail.

All the signs are that it will never be fixed.  If I'm wrong here, set
yourself a deadline for fixing it and let us know what that deadline is.
