Twenty Twenty: button block does not act on appearance change.

[himshekhar07]

Steps to reproduce the issue:-

1. Activate Twenty Twenty theme.
2. Choose a button block.
3. Change appearance to bold, semibold or anyone.

You can be able to see any changes in the letter.

I have attached a video for better understanding.

I can confirm hitting the same issue if Theme 2020 is active.

I also ran some more tests on other themes and here are the results:

• 2020 - Issue with appearance, Lettercase, letter spacing (also raised under https://core.trac.wordpress.org/ticket/58024)
• 2021 - Issue with appearance and line height
• 2022 and 2023 - No issues encountered

Tested on
Chrome (Version 111.0.5563.146 (Official Build) (x86_64))
Mac OS Monterey 12.6.3
WordPress version 6.1.1
PHP 7.4

This is happening for me when creating blank theme with "Create Block Theme" plugin, so I don't think it's limited to Twenty Twenty theme.
