Leverage the accessibility tree for the Navigation Engine

[dhuynh95]

Someone rightly pointed yesterday that we could use the accessibility tree during the webinar.
Got to say I heard of it but haven't checked.

I think this is something where the community could help.

We will draw the details of implementation with @mbrunel and @HiImMadness and share the steps to implement it here

In the same vein we can use the for attribute to enrich element context even when aria-label is absent.

<label for="abc">Search</label>
<input id="abc" />

input#abc has no information itself, but we can infer a "Search" label.
