Grammarly causing WordPress to shake while in editing mode

[westnz]

Description

Screen shaking while in editing mode. It disappeared for some users when they turned Grammarly off.

Step-by-step reproduction instructions

1. Edit your site or write a P2 post while having Grammarly installed on your site.
2. I'm unsure if you will be able to reproduce this issue, as only some folks indicated that they experienced it. I'm also unsure if the issue has been resolved, but we probably want to avoid this from happening again. Someone also wrote: "It looks like Grammarly has shipped an update. I can no longer replicate my original issue in the post editor." I can also confirm that I experienced this problem.
3. Please see this thread from the .Org Forum: https://wordpress.org/support/topic/wordpress-shaking-while-in-edit-mode/#post-18139467
