Re: [csswg-drafts] [css-view-transitions-2] How should view transitions be wired up in frame-timed update loops? (#12125)

> Doesn't mithril have an "update now" sort of function, like React's `flushSync`? That would be my first place to look if I was to integrate view transitions with a framework I'm not familiar with (and the way to integrate view transitions with React before the built-in support was en-route).

We do allow synchronous renders with `m.redraw.sync()`. However, the `popstate` handler updates the router's state asynchronously, so you can't just do `m.route.set("/path"); document.startViewTransition(m.redraw.sync)` and call it a day.

Also, neither us nor React Router provide hooks to generically intercept route changes to manually schedule the sync update. This not only complicates the state update even for React users, it also 1. introduces non-determinism depending on when the browser flushes the transition update and 2. causes the whole thing to not even be usable at all with the back and forward buttons.
