CKEditor 5 dropdown styles empty

Arun.B → made their first commit to this issue’s fork.

Hi taote,
I tried to reproduce this issue but its working fine for me in Drupal 10. Can you provide steps to reproduce the issue?
Here is the screenshot of my instance.

Just tested this on a fresh 10.1 install and did not notice the problem.

The screenshot I don't see the styles button enabled?

Also the style you are using is for an H2 so it wouldn't become available until an H2 is placed in the editor.

Removing credit for Arun.B for the empty commit.

smustgrave you are right, my fault. The problem was that the cursor wasn't positioned on an element that could be styled. I'm used to CKEditor4, where I don't think this happens. Sorry.
