you were right!

it took me some time to test all cases manually and migrated them to playwright - but it behaves exactly as you described
github.com/jantimon/rea...

I also ran the playwright tests with react-compiler and the results were quite impressive

Here is Apple.⁠com struggling with these viewport bugs:

I am working on a css-in-js lib which supports the styled-component syntax which compiles in rust (full HMR 27ms) and has no runtime

would that help with your pain points?
