Netlify CMS Dashboard sluggish when there are many objects in a list

[vai0]

Describe the bug
Not really a bug per say - but my current implementation has a list field that contains 25 objects. When typing in any of the other fields on the page, or adding a new object to the list, there's a noticeable delay.

To Reproduce
This can be reproduced in the kitchen sink demo. Add up to around 20'ish objects into the List field. Try filling in one of those objects, or typing in another field on the page. There's a half a second delay for every character typed or dropdown opened, toggle switched, etc....

Expected behavior
Expect there to be a much more minimal delay.
