Error when autofilling fields for logging in with password managers

Steps to reproduce

1-Have a form widget with email and password inputs. 2-Ensure that the email input has autofillHints set to: [AutofillHints.username, AutofillHints.email]. 3-Ensure that the password input has autofillHints set to: [AutofillHints.password]. 4-Attempt to use password managers such as 1Password, Bitwarden, etc 5-Notice that the fields are recognized but do not auto-complete. 6-Note that in some cases, the input loses focus.

Expected results

The expected behavior should be that autofilled inputs fields are automatically populated using password managers for Flutter web, especially since several users use password managers.

Actual results

Autofilled inputs are not populated with password handlers for flutter web

Code sample

```dart class AutofillTestView extends StatelessWidget { const AutofillTestView({super.key}); @override Widget build(BuildContext context) { final TextEditingController email = TextEditingController(); final TextEditingController password = TextEditingController(); return Column( mainAxisAlignment: MainAxisAlignment.center, children: [ Form( child: SizedBox( width: 300, child: Column( children: [ TextFormField( controller: email, keyboardType: TextInputType.text, autofillHints: [AutofillHints.username, AutofillHints.email], decoration: InputDecoration( errorMaxLines: 3, labelText: "Email", ), ), TextFormField( controller: password, autofillHints: [AutofillHints.password], decoration: InputDecoration( errorMaxLines: 3, labelText: "Password", ), ), ], ), )) ], ); } } ```
