Today's Highlight

The most interesting thread today was the renewed discussion on createPortal event propagation, with both Dan Abramov and Sebastian Markbåge weighing in. This issue (opened back in 2017!) asks for a way to stop React synthetic events from bubbling through portals in the React tree — a pain point for modal/dropdown implementations. Having two React core team members active on it suggests this might finally be getting attention.

Also notable: Theo Browne submitting a PR to claude-code to remove a "retro-futuristic" design recommendation from AI coding skills — a fun meta-moment of developers shaping how AI tools approach frontend design.
