FF104 HTMLElement.focus() param focusVisible

[hamishwillee]

FF104 adds support for HTMLElement.focus() param focusVisible in https://bugzilla.mozilla.org/show_bug.cgi?id=1765083.

This is not supported in chromium or webkit yet, though there are bugs https://bugs.chromium.org/p/chromium/issues/detail?id=1317039 and https://bugs.webkit.org/show_bug.cgi?id=242456

Related docs work can be tracked in mdn/content#19302
