[css-lists] Should marker obey text properties?

[Loirooriol]

CSS Text properties don't apply to ::marker.

However, they are inheritable, so you can set them to the list item and observe the effect.

<ol class="type-roman"><li>content</li></ol>
<ol class="type-string"><li>content</li></ol>
<ol class="marker-roman"><li>content</li></ol>
<ol class="marker-string"><li>content</li></ol>

li { text-transform: uppercase }
.type-roman { list-style-type: lower-roman }
.type-string { list-style-type: 'i. ' }
.marker-roman ::marker { content: counter(list-item, lower-roman) '. ' }
.marker-string ::marker { content: 'i. ' }

Firefox renders it as

i. CONTENT
i. CONTENT
 I.CONTENT
 I.CONTENT

So it seems ::marker's content obeys text-transform just like a ::before would do, but list-style-type does not. But I guess https://bugzil.la/1542807 may make list-style-type obey text-transform.

(Also note that list-style-type behaves like there were white-space: pre, ::marker's content does not. Is this expected?).

Note that Chromium doesn't support ::marker yet, but recently I implemented list-style-type: <string>. With LayoutNG, the result looks like

I. CONTENT
I. CONTENT
1. CONTENT
1. CONTENT

So list-style-type obeys text-transform. But in legacy, list-style-type behaves like in Firefox:

i. CONTENT
i. CONTENT
1. CONTENT
1. CONTENT

What's the expected behavior?

OK so I just noticed there already was #4206 about this. But this has more context and subcases, so I will copy the info there.
