Unexpected behavior some in inline tools style

Describe a bug.

Steps to reproduce:
1. I create a paragraph and add some text
2. I apply some inline styles from the inline tool: Bold, italic, marker, and inline code
3. I delete the text and write something again and I see the same style applied, witch I think it is correct
4. I open the inline tool and I see the bold and the italic icons with active class, but marker and inline code are not.

Expected behavior:
I should see all the activated icons
