LiveData's "More actions" (kebab) dropdown menu is not reachable using the keyboard

The more action menu is skipped because it's incorrect HTML.It pretty much goes like this:
Links are navigation tools. Every link has an href to give the navigation direction.
If a link has no href then it does not do anything and we shouldn't expose it.

Source: `If the a element has no href attribute, then the element represents a placeholder for where a link might otherwise have been placed, if it had been relevant, consisting of just the element's contents.` from https://html.spec.whatwg.org/multipage/text-level-semantics.html#the-a-element

Note that there's a very similar problem with the panel (sort, filter, properties,...) controls.
In this case it's just because the controls are spans with hard-coded listeners.
