v2: Underline does not appear to be supported

[ssteffanus12]

Relevant packages:

• react-quill: 2.0.0
• draftjs-to-html: 0.9.1
• react: 17.0.2

For context, I've been a long-time user of draft-js, but since that project has been abandoned I've needed to switch to something newer, while maintaining support for a database that already contains draft-js json blobs... hence why I'm using draftToHtml to convert them to html snippets below.

Example code:

const TextViewer = ({ classes, data }) => {
    let content = "";
    if (data) {
        content = draftToHtml(data);
        console.log(content);
        /* prints <p><ins>message</ins></p> */
    }

   /* displays the text "message" without an underline */
    return (
        <div className={classes.root}>
            <QuillEditor
                className={classes.editor}
                value={content}
                readOnly
                theme="bubble"
            />
        </div>
    );
};
