We’ve entered this phase of the blog post.

@jakearchibald.com plz fix

This was almost certainly a skill issue on my part. 😅

Here are the horrors if you want to have a go at figuring it out: github.com/samwho/visua...

The animations consistently didn’t play for me, but only on Firefox and only after the site been deployed. I couldn’t reproduce it locally, despite the code being identical. Leads me to believe it’s a timing problem, though I never did try network slowness emulation in the dev tools 🤔

The thing is that Firefox on iOS is not even Firefox. But whenever I see multiple rAF's nested, especially with a setTimeout sprinkled in, I gotta summon Jake.

huh yeah. Did Chrome iOS have the same issue?

No.

Huh, yeah, that's very weird, since it's the same rendering engine.

Sorry, just realised the link isn’t anywhere in the thread: samwho.dev/big-o.

It occurs to me that it isn't a good idea to deploy a broken version of a post that's still sort of doing the rounds, so I've hidden the broken version behind a query param: samwho.dev/big-o?broken=1.

Curiouser and curiouser! It worked for me in FF the first time, then stopped working after I refreshed. Relaunching the browser exhibited the same pattern: worked once, but not again Same with loading the page in a new tab

I don't have an iOS device so I wasn't able to dig into it myself, but I've filed bugzilla.mozilla.org/show_bug.cgi.... Add any details you wish, but let me know if the demo link is likely to stop working (…or stop not working, you know what I mean)

I mean, something working in one browser and not the other is a failure of either interoperability or specification.

*or testing*

I guess I grouped all kinds of implementation bugs into the "interoperability" category. Probably not super fair to folks working on interop 😅

Self-deprecation is the language of my people.

I had to learn it for my UK citizenship test. I didn't do very well, just barely enough to pass.
