Description
On macOS, system-level autocomplete suggestions appear in <textarea> elements even when all relevant HTML attributes intended to disable autocomplete and text assistance are explicitly set.
Is this behavior intentional, or is there any supported way for developers to control or disable this functionality?
Steps to Reproduce
- Send yourself an email using the native macOS Mail app containing a verification code (for example).
- Focus an HTML
<textarea>element in any web application. - Focus the textarea.
Expected Result
The autocomplete popup should be controllable from the code, and it should be possible to fully disable it using standard HTML attributes or browser APIs.
Actual Result
The system autocomplete popup appears in all cases and cannot be controlled or disabled by the code, even when all known attributes (autocomplete="off", autocorrect="off", autocapitalize="off", spellcheck="false") are set.
