HTML writer: Allow "spanlike" classes to be combined. Previously classes like "underline" and "marked" had to be the first class in a span in order for the span to be interpreted as a "ul" or "mark" element. This commit allows these special classes to be "stacked," e.g. `[test]{.mark .underline}`; in addition, the special classes are no longer required to come first in the list of classes. See #8194 for context. 2022-07-25 20:55:48 +02:00			```
