An unpleasant little thing when updating WordPress to version 5.8.2

Hello!

When updating WordPress to the current version (5.8.2), I noticed that the text font in the Gutenberg block editor differs from that used in the theme, although before everything was identical: the same text in the editor on the site.
I understand, a trifle, but suddenly something else affected the last update and decided to inform you.

Sincerely.
