details-marker pseudoclass

[gampleman]

When I write summary::details-marker { /*something */} I would expect autoprefixer to emit something like summary::-webkit-details-marker, summary::details-marker { /* something */} for me, but it doesn't appear to do so.

Does it described in any CSS specification or it private extension for Safari?

It's supported by Chrome as well. I found this discussion about it: whatwg/html#722. Seems like this feature might not be going anywhere much. The main reason you want it is to call display: none on it, so that it doesn't show up in those browsers. My main motivation in filing this issue, is that I sort of expected it to add the prefix for me, but it didn't.

Sorry, there is no unprefixed version yet, so it is just ::-webkit-details-marker, there is no ::details-marker
