This commit makes a few changes:
- Link preview views are no longer cached, only the metadata. This fixes
a memory leak when preview videos. It will keep playing the video
forever eventually leading to a crash. This is fixed!
- Cache the intrinsic height of previews, when loading notes it looks
for the cached height so that things don't pop-in after the fact
- Note artifacts and previews are set in the constructor instead of
onAppear, this prevents the size from changing and popping after it
has been loaded into the lazyvstack
Changelog-Fixed: Fix memory leak with inline videos
Changelog-Fixed: Eliminate popping when scrolling
