is-valid-autocomplete missing token

[Mottie]

Product

axe-core

Product Version

4.5.2

Latest Version

• I have tested the issue with the latest version of the product

Issue Description

Expectation

Allow "webauthn" as a token in the autocomplete attribute with a maximum of 5 tokens.

Actual

Shows an "autocomplete attribute must be used correctly" issue

How to Reproduce

Test with "webauthn" in the autocomplete value

<input required autocomplete="webauthn work email" type="email" name="email" id="work_email">

Additional context

• webauthn in HTML standard
• table showing 5 token max
• It's difficult for me to make sense of the spec, but "the user agent should show public key credentials available via conditional mediation when the user interacts with the form control" seems to include values like "silent", "required", "conditional", etc?
• webauthn is only valid for input and textarea elements.

Note: I don't have a need for this addition, it's just something I noticed while trying to figure out if section- can be followed by any text.

webauthn is new in HTML. It wasn't there when we built this. Thank you for sharing. We'll be sure to update.

Validated with the latest axe-core develop branch code base,
autocomplete-valid rule now allowing for webauthn which was not implemented earlier.
Here auto-complete-valid rule is failing when we pass webauthn as webauthn work email
Passing for the below webauthn tokens

autocomplete="email webauthn" 
 autocomplete="section-foo email webauthn" 
 autocomplete="section-foo work email webauthn" 
 autocomplete="section-foo billing work email webauthn"
