[css-text] Reconsider the resolution on #855 #5410
Description
In #855 it was resolved that CR gets treated as any other control char, but looking at the history, we had to make it render invisible in https://bugzilla.mozilla.org/show_bug.cgi?id=941940 for compat reasons.
It seems Gecko and WebKit render it invisible, and Blink just treats lone CRs as an space. Probably both behaviors are acceptable compat-wise, but that doesn't match the spec.
