## Description
Firefox's UA stylesheet already sets `iframe:focus-visible {
outline-style: none; }`, so Preflight's `:-moz-focusring { outline:
auto; }` rule overrides that and applies an unwanted auto outline to
focused iframes.
Adding `:where(:not(iframe))` to the selector preserves the improved
focus ring behavior for all other elements while respecting Firefox's
native iframe focus styling.
Fixes #19795
