What happened?

Description

It feels like there's some kind of minor UI performance issue when deselecting elements in Craft 5's element indexes (and element select modals).

I don't know if it's possible to tell from the screencast below, but in reality there's a very noticeable and consistent ~>0.5s delay from clicking a selected element, to the element actually appearing as deselected/selectable:

Selecting elements is instant, and the UI in general feels very performant, which makes the slower deselect action all the more noticeable.

I tested this on a few different browsers (including the latest Chrome and Edge) on a couple of different Macs (including an M1) and FWIW the behavior and performance seems pretty much the same everywhere.

Obviously this isn't the biggest problem in the world. Deselecting elements is a very common action though, so it'd be nice if it felt as spiffy as everything else 😊

Steps to reproduce

1. Select an element in an element index or select modal
2. De-select the element

Expected behavior

Deselecting elements should be instant.

Actual behavior

The action of deselecting elements is noticeably slower than selecting elements, giving the impression that there's some kind of JS performance issue under the hood.
