Unable to Correctly Render Colored Text in Ghost

Developer help
1

Description

I am trying to extend the Ghost editor by adding a button that allows setting text color. However, I found that this functionality does not work as expected.

Specifically, when I set the text color and save the post, the lexical field correctly records the <span> tags with the style attribute, but the html and plaintext fields have the <span> tags with color removed.

Steps to Reproduce

  1. Select some text in the editor.
  2. Click the color button I added and set the text color (e.g., red).
  3. Save the post.
  4. Check the fields in the database and observe that the lexical field correctly records the <span> tags with the style attribute, whereas the html and plaintext fields have the <span> tags with the color removed.

Expected Behavior

After saving the post, the html and plaintext fields should retain the <span> tags with color styles, and the colored text should render correctly on the front end.

Actual Behavior

After saving the post, the html and plaintext fields have the <span> tags with color styles removed.

Additional Notes

I would appreciate any guidance on how to retain the color styles in the html and plaintext fields, ensuring that the colored text is rendered correctly just like in the lexical field.
