Issue:
TextEditor: cannot combine underline and smal/huge size of font
### Describe the bug

When you are using a p:textEditor you cannot set the "huge" size then underline the text, only underline will be taken into account.

### Reproducer

1. Go to https://www.primefaces.org/showcase/ui/input/textEditor.xhtml?jfwid=c7208
2. Enter any text
3. Select the text
4. Select "huge" size
5. Select the text
6. Select "underline"
7. Click on save (it will trigger the behaviour)
8. Résult: 
![text is not huge](https://github.com/primefaces/primefaces/assets/1523653/af4c6991-ed2f-453e-919b-81b89b293fe0)


### Expected behavior

The text must be huge (the same way it is before you click on save) :
