[css-view-transitions-1] How should view transitions be wired up in frame-timed update loops?

[dead-claudia]

I got a question about how to integrate view transitions with Mithril, and it's very awkward to integrate. In fact, in the face of frame-timed updates, it ends up actively causing glitchiness, and that very thread ran into such a real-world integration problem.

Mithril, like many frameworks, batches its DOM updates to run all at once within animation frame callbacks for performance.

One of the cause of problems I suspect is exactly that animation frame batching. Microtasks scheduled within renders are delayed until after the DOM is consumed for paint. And I could see this causing timing delays and other glitches during update.
