Test please. Look at strong password tests for examples.  Indentation of case statements look off, like tabs or something. Fix. Make sure no tab chars in files

Good start, but this patch is missing invalidation logic to handle things like (off the top of my head):

1. Form reset - grep for ::reset
2. When HTML type attribute changes
3. When HTML value attribute changes


(2) and (3) call :: resignStrongPasswordAppearance. <— Grep that, it needs to be patched. Look at all callers, more patching may be needed.

In my opinion I would share with ^^^^ selectors instead of duplicating.

This looks really good.

Bug title should be fixed 🙂:

Clients => clients

> Source/WebCore/ChangeLog:6
> +

I feel that the title is hard to read and confuses me. I don't understand how a field can be considered "secure" and viewable. <-- I know what you mean by reading the patch, but that's not how I would describe this change. Can we please improve the title? If not, please provide a more elaborated description of the purpose of this change under the "Reviewed by" line.

This is duplicating the properties of input:-webkit-autofill-strong-password (above). Please share.

This duplicates the code in <https://trac.webkit.org/browser/webkit/trunk/LayoutTests/fast/forms/auto-fill-button/resources/process-auto-fill-button-type-and-invoke-runTest.js>. Only difference is checking for inputElement.dataset.autoFilledAndViewable. Please modify process-auto-fill-button-type-and-invoke-runTest.js instead of duplicating it.

I just realized that this patch does not handle the case where the field's value changes programmatically. We need to patch up setValueFromRenderer()

Actually, I'm not sure what you intended the behavior to be for this feature when this happens. Either need to patch up setValueFromRenderer () or code is okay as-is and you just need to explain in the ChangeLog why we don't need to touch setValueFromRenderer().

As per off-line discussion, behavior is intentional and WebCore ChangeLog updated to describe the reason why we don't change setValueFromRenderer.
