Add support for `::marker`

[lukewarlow]

Autoprefixer should add a ::-webkit-details-marker fallback for ::marker .

This is because Safari currently only supports the ::marker pseudo element with lists but not detail elements.

Not sure on how best to implement this as Safari shows as supporting the unprefixed version in caniuse.

Looks like it is work for separated plugin (like we had for flexbox bugs).

@ai any updates on this plugin?

@lifeiscontent I do not plan to create it. You can create.

Here is a good guide: https://postcss.org/docs/writing-a-postcss-plugin

@ai if I created the plugin would you host it on the postcss org so it gets a bit more visibility?

[ai]

@lifeiscontent org doesn’t give a lot of visibility. It is better to mention it in @Autoprefixer and @PostCSS twitter accounts and add it to https://www.postcss.parts/
