Subject: [PATCH] Revert "Revert option to collapse long notes (Misskey PR
 8561)"

This reverts commit 71150f21cd91df7bdd78a8f708db092418e85baa and reinstates
the option to collapse long notes again after they were expanded.

It is unclear why this commit was reverted in the first place, syuilo
claimed there to be issues with URL previews and attached images. These
problems could not be reproduced when testing.
