hellofromTonya e8096f0883 Editor: Add 'wp-polyfill' to _wp_get_iframed_editor_assets() for inert attribute in Firefox. ...

Adds the polyfill script to the iframe to make the `inert` attribute work correctly in Firefox. This solves the problem that the site editor can operate on the block editor in Firefox even in browse mode.

Why?

The inert attribute is intended to render the element and its sub-tree elements `inert`, but Firefox doesn't support this attribute. For the `inert` attribute to work as intended in Firefox, even within an iframe, the script needs to be injected into the iframe as well as the global document.
