Creates its own file picker UI with a button and file name display - Implements all HTMLInputElement properties (files, name, value, validity, etc.) - Uses ElementInternals for form participation when available - Provides validation methods (setCustomValidity, reportValidity, checkValidity) - Shows current file value for ClearableFileInput compatibility - All JavaScript and non-Selenium Python tests pass Note: Selenium tests need updating as the hidden input is now created dynamically by the custom element's JavaScript.
