Re: [csswg-drafts] [css-text-3] The web de-facto requires NULL U+0000 to not be visible (#6983)

Firefox has an `about:config` setting `layout.css.control-characters.visible` that controls whether control characters are rendered visibly. Currently, this is enabled in Nightly builds, but disabled for the Beta and Release channels.

When `layout.css.control-characters.visible` is set to `true`, U+0000 is rendered as a visible "hexbox" glyph just like other control characters. I'm not aware of any reports of this being noticed in the wild (as has occasionally happened for other control codes), though perhaps shipping it more widely will unearth a few cases.
