Re: [csswg-drafts] [css-lists] How should spaces be treated in markers? (#4448)

Here's my proposal for this issue:
1. Add `white-space` as a property that applies to `::marker`
2. Add `::marker { white-space:pre }` to the UA sheet
3. Mention that an [outside](https://drafts.csswg.org/css-lists/#list-style-position-outside) `::marker` box has its `display` value [blockified](https://drafts.csswg.org/css-display/#blockify). (This makes it clear that if an author overrides white-space with say `white-space:normal` then any trailing space in an outside marker's text is expected to be truncated as it normally would at the line end in a block.)

I think those changes would define how white-space should be handled unambiguously.
I think we can punt on the other issues for now (multiline marker, allowing more properties etc).
