Are you saying that discarding SPACE inside “code spans” delimited by GRAVE ACCENT was the intended behaviour?
I have actually started to use U+23B5 BOTTOM SQUARE BRACKET as a stand-in for SPACE where it is important (pasted into the text via clipboard!), because not only SPACE but NO-BREAK SPACE would get removed by the parser without trace.
I would for sure welcome the preservation of SPACE in code spans! – See my rant at the end of my post here for details.
