Intent to unship: ::-moz-math-anonymous.

[Emilio Cobos Álvarez]

Hi,

In bug 1439837 I intend to remove access to the ::-moz-math-anonymous
pseudo-element.

This is a Gecko-only pseudo-element that is there since the initial
Gecko export, and is only used to get a style inheriting from another
one for some MathML characters, so it has no good reason to be exposed
to the web at all.

I'm not aware of anything or anyone using it apart from us.

SGTM. I did not find any references on MDN, so nothing to update there AFAIK.

However with a broader web search I found https://gist.github.com/yields/6648240

Is ::-moz-math-anonymous special? (last of its kind?) Or would the
same reasoning apply to removing access to ::-moz-math-stretchy or any
of the others in that list? Or is that just an out-of-date list that
we can ignore?

Thanks,

Tantek

P.S. I also found moz-math-anonymous on
http://mdn.beonex.com/en/CSS_Reference/Mozilla_Extensions.html#Pseudo-elements_and_pseudo-classes
but that seems to just be an out-of-date copy of
https://developer.mozilla.org/en-US/docs/Web/CSS/Mozilla_Extensions#Pseudo-elements_and_pseudo-classes
which already removed the -moz-math- pseudos.

Looks out of date to me. ::-moz-math-stretchy was removed four years ago
in https://bugzilla.mozilla.org/show_bug.cgi?id=1000879.

Hi Emilio,

IIRC, ::-moz-math-stretchy was the only MathML pseudo element that was
publicly documented but it's no longer needed now that people can just
use font-family and/or the font preference menu to select a math font.
It should be safe to stop exposing -moz-math-anonymous and
-moz-mathml-anonymous-block, if we do.

Thanks for confirming that Fred!

Just for the record, ::-moz-mathml-anonymous-block is already not
exposed, since it's an anonymous box. This looks to be the case since
https://bugzilla.mozilla.org/show_bug.cgi?id=377824.
