Twenty Twenty-Three: Sticky posts not visually different than regular posts

[bgturner]

When a sticky post exists, it isn't styled differently than other posts.

The TT3 theme correctly:

• Puts a sticky post as first in the blog roll
• Applies the sticky class
• Also shows the post in the original position, without the sticky class

This was found when doing QA of the 6.1 release candidate:

Replication

• Install 6.1 and be sure that TT3 is active
• Import the theme unit test data:
  • ​https://github.com/WPTT/theme-test-data
• Navigate to the posts homepage and note that the sticky post doesn't look visually different than other posts but it does have the correct sticky class
• Navigate to older posts until you find the sticky post where it should be. Note that it correctly does not have the sticky class

Here's a screenshot to help visualize:

I did not understand in what way this is a bug?
I believe it is a design decision.

With the introduction of the Custom CSS field in 6.2, the user has easier access to adding their own styles to the .sticky class. Does that solve the issue?
