Quick overview opening slowly on larger presentations

[jakobkordez]

Quick overview takes a few seconds to open on large presentations (400 slides).
This is a big problem when I want to quickly jump to a slide.

This problem occurs because a very large amount of DOM elements need to be added during opening.

This problem was fixed in #1610 but was never merged.

Is there a possibility of this being merged if I resolve the conflicts or should I just create a fork for my personal use?

Anthony wrote #1843 after that. Is that helpful?🤔

It does not work. I added the overviewSnapshots: true to the frontmatter but opening the quick overview takes a few seconds then my console starts spamming [Slidev] Snapshot captured for slide xxx and a bunch of [Vue warn] warnings. All of the slides get replaced with the symbols for missing images.
Even after all the slides have been replaced with missing images, opening and closing the quick overview takes a second, compared to the instantaneous opening and closing in my implementation.
Running build and then serving dist/ does not make a difference.
