Thanks for doing this! This is indeed the maximally clear form for providing an interoperable spec others could implement, even if currently there is no other implementer interest. Great stuff.
So, despite this not likely being merged soon, I went through and did a quick review, which I hope is helpful.

It turns out we recently discovered CEReactions is not necessary for DOMTokenList attributes: #2378. (It's actually disallowed these days.)

Style nit: this seems like a normative "may", not a "might". I'd then move the example to
<p class="example">A user agent might ignore the <code data-x="attr-media-controlslist-nofullscreen">nofullscreen</code>

It might be worth adding something like
<p class="note">Hiding these aspects of the user agent's own controls does not necessarily disable
the related functionality. For example, the user agent might present the same functionality through a
context menu or keyboard shortcut.</p>Adds a DOMTokenList backed controlsList/controlslist attribute to HTMLMediaElement with three keywords: nodownload, nofullscreen and noremoteplayback.

Closing as this seems abandoned. |
|
I believe this is shipping in Chrome so I think it's best to leave open as a record of such? If we want to start closing single-vendor PRs then I at least would want to work on some sort of archive... |
|
Agreed! |
|
Can't "a record of such" be in Chrome's documentation? I don't think we should leave PRs open for years and years if it's pretty clear it's not going to get the multi-implementer interest it needs to land. |
Alternately, a closed PR is literally "a record of such". PRs don't stop existing when they get closed. |
|
For info, the Chrome team is thinking about adding another value |
|
Yes, that plus a rebase would be ideal. |
|
@domenic Is it even possible for me to update this PR as I'm not the original owner? |
|
You would need to get write access to @avayvod's fork. Otherwise creating a new PR would make the most sense. |
|
Rolling forward to #6715. |
Adds a controlslist content attribute reflected by a DOMTokenList dom
attribute named controlsList to the HTMLMediaElement and
<audio>/<video>tags.
Specifies three supported keywords: nodownload, nofullscreen, and
noremoteplayback.
Documents the change proposed in #2293 (unlikely to be merged).
