I'm sure there's a lot of important details missing here, but it might be useful to have something written down to point to and work out the details over PRs and issues. WDYT? |

I agree, but the plan was to put it into Overflow L5 along with the current fragmentation appendix, not to patch Overflow L4. :) #9745 (comment) Wrt the content of this, I think it needs more explanation of the use cases it's trying to solve (and the use case it's not trying to solve). For my part, I don't understand why we aren't trying to solve the "highlight the relevant table of contents entry" item along with this, for example. The part about only the currently-active scroll marker being focusable is also weird. How do you activate a scroll marker control with the keyboard if it's not focusable? |
::scroll-marker-group pseudo element acts as an area to which ::scroll-marker pseudo elements are flowed. It is a container for `navigation dots` of carousel (e.g. dots for choosing image in gallery). ::scroll-marker-group is the first/last child of the originating element, depending on the scroll-marker property (after/before/none). Note: if there is ::view-transition pseudo on the originating element, it would be the last child instead. Note: this CL places box of ::scroll-marker-group as a child of originating element instead of prev/next sibling of it for now. This will be fixed in following CLs. No AX actions are needed, since ::scroll-marker-group acts as a container for ::scroll-marker pseudo elements. AX tests will be added with ::scroll-marker CL.
