aria-required fails on combobox without aria-expanded

[straker]

This should not fail as pointed out in #2505 (comment)

<div role="combobox"></div>

Validated with the latest code ,
its giving failure for the below cases:
<div role="combobox"></div>
and
<div id="target" role="combobox" aria-expanded="true">expanded</div>

and as per the issue, if we are not passing any attributes for role=combobox means it is in collapsed state only ,
so that the snippet <div role="combobox"></div> meaning is expanded=false , so that it should not fail
but its showing as failure
@straker , can you please confirm, is the fix applicable only when aria-attributes state is mentioned?

[straker]

@padmavemulapati no attributes does not equate to expanded=false and aria-expanded is a required attribute which does not have an implicit value defined (so no default) https://www.w3.org/TR/wai-aria-1.2/#combobox

@straker , Thank you for the clarification.

This has been mentioned by the Angular team as being a false positive, as the aria-controls attribute is added once the dropdown for the select with role "combobox" is added to the dom.

It seems as though this is still generating false positives. Any plans to address this @straker?

Thank you.

@mshubat The next axe-core release slated for the end of this month should include this fix.
