407011 - Remove plaintext rules in quirks.css

Status: RESOLVED WONTFIX

(Core :: Layout, defect, P3)

Attachment: patch

<multicol> isn't really supported by any real browser, so it seems to me that those rules can be removed from quirks.css.
I think the same applies for <plaintext>.

Also, I think that the margin rule for <plaintext> can be removed in html.css, because in IE, <plaintext> always seems to have margin:0.

So... I've certainly had long enough to think about this.  Sorry for the delay.

I guess I think if the rationale is that nobody supports this, we should be making a decision to remove it completely.  Removing a small percentage of the code to support these elements doesn't make much sense to me; there's still a good bit in the HTML parser.

(I'd also probably want to coordinate with any HTML5 spec work that's going on as far as actually doing that.)

So I think I prefer not to do this.  (So review- as a policy decision; not because there's anything actually wrong with the patch.)

There's also bug 734063. And in https://www.w3.org/Bugs/Public/show_bug.cgi?id=27672 I got the request to remove it from HTML, which I think I'll grant once a patch is submitted since Firefox is the only browser that supports it.

Per HTML currently, plaintext has default margins and the quirk. multicol has no default styles or quirks.

multicol was removed from the spec in https://github.com/whatwg/html/pull/238

multicol was removed in bug 1893342, updating this bug to only be about plaintext.

WONTFIX because the current spec includes plaintext
