[request] add data-tag for editing view (especially for lists)

[efemkay]

i hope u can consider extending this plugin's general features to editing view. i use bullets a lot (like roam or logseq) where there're header and sublists is the smaller header (per screenshot below).

currently obsidian does not provide class that identify the div contains bullet that also contains header (.cm-header-x). perhaps as starting point, giving data-tag for divs that has .cm-header-x properties, making the parent div identifiable as header div. in my case, i can add bottom border for the whole length of the div (not just the span), or even background color -- making them almost identical to reading view.

thanks.
