[iOS] Unable to autofill username-only pages in WKWebView
https://bugs.webkit.org/show_bug.cgi?id=273538
rdar://126970887
Reviewed by Wenson Hsieh and Abrar Rahman Protyasha.
As a result of UIKit / AutoFillUI changes in iOS 17.4, username autofill is now
displayed as a suggestion in the keyboard candidates bar on pages that separate
out their username and password fields, like yahoo.com. Previously, this
autofill flow was only available to pages that contained both a username and
password field together.
However, the introduction of standalone username support was a consequence of
other feature work, and never explicitly tested in WKWebView. Due to the way
autofill text suggestions are set up in WebKit, attempting to autofill a
standalone username field, simply drops the content.
Specifically, `AutofillElements::computeAutofillElements` returns `std::nullopt`
if no password field is present. This means that when a username is autofilled
using `-[WKContentView insertTextSuggestion:]` and
`WebPageProxy::autofillLoginCredentials`, the data is simply dropped by an
early return in `WebPage::autofillLoginCredentials`.
Fix by updating `AutofillElements::computeAutofillElements` to handle the
username-only case.
* Source/WebCore/editing/cocoa/AutofillElements.cpp:
(WebCore::AutofillElements::computeAutofillElements):
Support for autofilling specific fields is already present in
`AutofillElements::autofill`, which null checks each individual autofill
element, including the username field.
However, this method currently returns no elements in the case where only a
username field is present. Update to return the username field in the case
where the `autocomplete` value is "username". This restriction corresponds to
the specification of `UITextContentTypeUsername` on the UI process side.
