I’m using Quill.js and need to:

1. Make "small" the default text size when the editor loads.
2. Ensure the text size persists when the user types.
3. Keep the selected size after pressing Enter (right now, it resets to "normal" instead of keeping the selected size).

Problem:

• The editor starts with "small" ✅.
• If the user selects another size, it works while typing ✅.
• When the user presses Enter, the new line always switches to "normal" ❌ instead of keeping the selected size.
• The toolbar still shows the previously selected size, but newly typed text is actually "normal."

Code:

html:

<div class="col-12">
    <div class="form-group">
        <label for="editor-container-ar">Content Arabic
           <span class="required" style="color: red">*</span></label>
<div id="editor-container-ar" style="height: 300px;"
    class="ql-container flex-snow"></div> </div></div>

javascript:

<script type="text/javascript">
    $(document)
            .ready(
                    function() {
                        var contentInput = document.getElementById('contentAr');

                        // Initialize Quill editor
                        var quillAr = new Quill('#editor-container-ar', {
                            theme : 'snow',
                            modules : {

                    });
....

Issue:

• Even with this code, pressing Enter resets the text to "normal" instead of keeping the selected size.
• The toolbar still shows the correct size, but the actual text formatting is reset.
