Performance: Reduced responsiveness when using Annotations API

[moorscode]

Describe the bug

Since Yoast SEO 9.2 we have implemented the annotations API support.
This results in reduced responsiveness when typing, at least in two situations:

• When typing really fast
• When moving the cursor while typing

Which suggests that the problem is only amplified by doing faster or more actions together.

Events that are used (extracted from profiling in the browser):
Mouse movement: Gutenberg/editor/index.js: stopTypingOnMouseMove
Fast typing: Gutenberg/editor/index.js: key: "render"

Maybe related:
When using Yoast SEO 9.1 (no annotations API) the following issue manifests itself after ~26 items in the How-To block instead of ~15

To Reproduce
Steps to reproduce the behavior:

1. Type really fast (button-bash) - in gradual amounts the text is starting to stagger more and eventually just does not update until you stop typing

Or

1. Type with one hand and keep moving the mouse with the other
2. The text will not be updated until after the mouse has stopped moving

Expected behavior
I expect the text to be updated and rendered whenever I type.

Screenshots

When moving the mouse while typing, these are the performance tab results:

When typing very quickly, these are the performance tab results:
