fix: Parser string sanitizer

Parser methods use the parse.cleanString method internally
to clean up strings from markup. Before this commit, this method
did not clean up whitespace that was protected by the additional
trim-set passed to the function. This commit fixes this buggy behavior,
albeit not in an optimised fashion.
