Re: [csswg-drafts] [css-view-transitions-2] Extend `waitUntil` so that it can delay the start of the View Transition (animating phase) (#13013)

> If this is only for cross-document and should affect _captures_, it should look different and work before the `pagereveal` event somehow.

Spitting out some ideas:

- Maybe an extension to `<link rel="expect" blocking="render" …>` so that one can indicate it wants the contents of the linked to resources to be loaded? For `<img>` this would be the (computed) `[src]`, for `<video>` the `[poster]`, with other elements TBD. Would not solve the custom element use-case though (unless the author can set it up beforehand to have the correct aspect-ratio).
- Or maybe a way to have a VT force a re-capture? Would solve the custom element use-case.
- …?
