@litherum The spec had a definite heuristic using EAW, which is afaik, what Firefox implemented. This issue was opened asking for spaces to disappear in more cases, specifically when one side was ambiguous in cases where the content language was known to be CJY. The CSSWG discussed and resolved on that in https://lists.w3.org/Archives/Public/www-style/2016Oct/0068.html

I unfortunately tagged the Emoji discrepency against this issue in https://github.com/w3c/csswg-drafts/issues/337#issuecomment-379776875 ; it's actually a separate issue, that the various wingdings have different behavior because the EAW is not consistently assigned, and thus our transformation rules are weirdly inconsistent from an author's point of view. @frivoal proposed a solution to this by tailoring the EAW of Emoji as he describes in https://github.com/w3c/csswg-drafts/issues/337#issuecomment-444316214

I'm not entirely sure which part @kojiishi is objecting to. I'm OK if our space-collapsing heuristics are more limited than requested in the original issue, but having Emoji behave inconsistently is really weird and imho not acceptable. https://github.com/w3c/csswg-drafts/issues/337#issuecomment-446775351
