Hello @cemag44300,

Thank you for report and collaboration!

We tried to reproduce the issue on 2.4-develop.
The issue is reproducible, please refer the below screencast.

1248026e-aaa0-4e09-bc1a-72ee9935f9dc.mp4

As we can see in the screencast, We are not getting the custom "style formats" in TinyMCE editor.

Hence confirming the issue.

Below is the module.

Thanks.
