Description

With further development of the HTML standard there have been introduced a number of new global attributes of which some are also applicable on form elements. To support these new attributes i have decided to extend the existing whitelist of global attributes that's being used in the rendering process and added the attributes listed on MDN which were missing.
As suggested by @froschdesign on slack i've commented out the ones i perceived as not really useful in context of form elements.

The following attributes have been added:

• autocapitalize - automatically cases typed content
• enterkeyhint - relevant for virtual keyboard contexts
• inputmode - relevant for virtual keyboard contexts
• is - support for HTML custom elements
• itemid - commented out since Microdata on input elements didn't exactly make sense to me
• nonce - commented out since afaik they're only relevant for <script> and <style> or similar tags
• part - for CSS styling
• slot - for shadow DOM usage
• translate - commented out since the description points to Text nodes inside elements

Should we at least document where these attributes come from? A link to their spec would be helpful 🤔

[Koopzington]

you mean inside the code, per attribute?
'autocapitalize' => true, // https://html.spec.whatwg.org/multipage/interaction.html#attr-autocapitalize

I don't know how prone the spec page is regarding breaking links, should they ever decide to move that blurp to another page.

Or a mention on https://docs.laminas.dev/laminas-form/v3/helper/abstract-helper/?

IMHO yes, per attribute pointing to whatwg.org is ok and enough. I wouldn't care about link stability, we can't be perfect.

Or a mention on https://docs.laminas.dev/laminas-form/v3/helper/abstract-helper/?

Listing each attribute would be cumbersome to me, but a mention that only some are supported with a call to look at Laminas\Form\View\Helper\AbstractHelper::$validGlobalAttributes to have the full list, that would be very welcome

LGTM, thanks for taking the time to expand on the references.

As for the CS failures, I think those are on our sude to adjust/fix (probably suppress)

[Koopzington]

Looks like i was a bit too hasty trying to fix things myself.
Should we use the snapshotted links now or not? :)

[Ocramius]

I don't mind - these are usually very stable regardless 👍

Thank you. I'll try to fix the CI once back from vacation 🏖️

Thank you @Koopzington
