[5.0.0]: Multiple console warnings when navigating element indexes

[thupsi]

What happened?

Description

When navigating element indexes, there are multiple warnings in the console. These are of two kinds:

1. [Violation] Forced reflow while executing JavaScript took <N>ms
2. [Violation] 'requestAnimationFrame' handler took <N>ms

Also, I'm not sure if this is related, but the loading of sources with many entries is somewhat slower than Craft 4.

This seems like the same issue as #14510, unless I’m missing something?

The issue you are referring to is about navigating nested elements. This one is about element indexes. They do have similarities though, and are possibly related.
