@gruber@mastodon.social The confirmation button is on the wrong side, and should instead be labelled “Dolt”

@cube_drone@mastodon.social Yes! For what it's worth, you can prod TikTok to give you a pretty wholesome high-quality feed by reinforcing what you want (swipe away or "not interested" and certainly don't comment or spread the bad stuff). But that doesn't fix the fact everybody else is getting the bad stuff

@drott@chaos.social Interesting – weirdly in my own test 🧺 and 🫠 do not trigger the bug at all, laying out in 0.2ms whereas ❤️ and 🤯 take about 1550ms. It seems there's a technique used in the heart glyph that triggers a bad path in Safari that not all glyphs use.

@cheesemaker Haha, what? Like your app couldn’t render my article, so you asked Claude to use the techniques in that article to debug the app? 🤯

@tom@typo.social Interesting! I'm still seeing 1600ms main-thread-blocking Layout to display a single Noto Color Emoji heart in desktop Safari (26.3). Is that expected?
