@EisenbergEffect @claviska Right. There are some things, but it depends on exactly what you mean by “reusability”.

@elonmusk @elonmusk, fake news! You built some great companies that are good for the planet. Why did you have to turn into such an asshole?

Mutation events will be removed from Chrome this month...

We've now got MDN docs published for all of the CSS Anchor Positioning features, including the position-try mechanisms. Get started at https://t.co/ahHna1eDlm. Thanks again to @estellevw for working with me on this!

@arithmoquine What is theta (the angle) in these heat maps? The radius lines up with my expectations, but whatever’s at 45 degrees is something we all can agree on!

“Post-truth is pre-fascism” - Timothy Snyder. Great quote. It’s unfortunate that those it’s aimed at don’t have the wherewithal to understand it.

@rniwa_dev Adoption is so central to the html spec that the spec even has its own adoption agency… https://t.co/FBztAhsPQd

@osilander Super short sided! I’m glad you’ve got something lined up.

Having said that, I think I’ve been waiting my whole life to say: at least you showed strong antidisestablishmentarianism.

@luke_warlow @igalia Congrats Luke! Great hire for Igalia.

@SFBART when things aren't going well, as they aren't this morning, it'd help to tell people what's really going on. We all have to plan around you, and information helps.

This is an awesome overview by @hdv on the new popover API. I highly recommend giving it a read.

[Mason Freed @Mfreed777]

@brucel Interesting bug! I agree that it'd be nice to have this as a bug, if you're willing: https://t.co/3VajTMNc0f.
My first reaction is: shouldn't `<video style="display:none">` never play audio?

@briankardell Well, I meant arbitrary content inside a select list, not necessarily specifically MathML. But MathML is good too!

[Greg Whitworth @gregwhitworth]

What @openuicg is trying to tackle is not easy. I greatly appreciate @davidbaron comment that matches my sentiments on a slight hurdle towards style able and extensible components/controls: https://t.co/80nXKX4Uns

[Mason Freed @Mfreed777]

@ElliottZ @gregwhitworth @kennethrohde @openuicg Yeah this is pretty much a no-go security-wise. Since a definite requirement is arbitrary HTML and styling, you can’t have it escape the bounds of the page/frame.
We added a use counter for selects escaping window bounds and it’s 0.08% of page loads. https://t.co/wyx2GuHkrw

[Mason Freed @Mfreed777]

@kennethrohde @gregwhitworth @openuicg That’s basically next on the list. But it’s challenging for sure.
