Request/Suggestion: reserve embed space to avoid page jitter.

[Prinny Mask]

When you go into a thread, the embeds load in one by one, and not always in a timely manner. This causes the newly loaded page to not be scrolled to where it should be, typically at the most recent new post.
Using CSS to reserve space for embeds would greatly reduce the amount of jitter new pages experience at load time.
Obviously some embeds will have variable height and this approach won't solve 100% of the troubles, but it would help a lot.
