I am working with a TestBlock in Optimizely CMS 12 and trying to configure the Title field with limited RichText settings. The Title field is defined as follows:

[CultureSpecific]
[Required]
[Display(Name = "Title", Order = 20, GroupName = CmsTabNames.Content)]
public virtual XhtmlString Title { get; set; }

My goal is to prevent TinyMCE from wrapping the content in <p> tags. However, despite configuring the forced_root_block setting, TinyMCE still automatically adds <p> tags when I add text to the field. Below is the configuration I am using:

context.Services.Configure<TinyMceConfiguration>(config =>
{
    // Text Styles
    var textStyles = new
    {
        title = "Text",
        items = new object[]
        {
            new { title = "Small Text", block = "small" },
            new { title = "Blockquote", block = "blockquote" }
        }
    };

    // Default configuration
    config.Default()
        .Height(200)
        .AddEpiserverSupport()
        .ContentCss("/assets/css/editor.css")
        .AddPlugin("table")
        .RemovePlugin("paste")
        .AddExternalPlugin("powerpaste", "/plugins/powerpaste/plugin.js")
        .Menubar("edit table")
        .AddSetting("paste_enable_default_filters", false)
        .AddPlugin("epi-link code epi-image-editor epi-dnd-processor epi-personalized-content media wordcount anchor textcolor colorpicker preview paste")
        .Toolbar("formatselect styleselect | bold italic underline strikethrough subscript superscript | alignleft aligncenter alignright alignjustify | numlist bullist indent outdent | " +
                 "table | epi-link anchor | image epi-image-editor media | epi-personalized-content | removeformat | searchreplace fullscreen preview | code | help")
        .StyleFormats(textStyles)
        .BlockFormats("Paragraph=p;Heading 1=h1;Heading 2=h2;Heading 3=h3;Heading 4=h4;Heading 5=h5;Heading 6=h6");

    // Limited RichText settings
    var limitedRichTextSettings = config.Default().Clone()
        .AddEpiserverSupport()
        .ContentCss("/assets/css/editor.css")
        .AddSetting("forced_root_block", "")
        .AddSetting("force_br_newlines", false)
        .AddSetting("force_p_newlines", false)
        .AddSetting("statusbar", false)
        .AddPlugin("code wordcount preview") // add epi-link anchor if links are needed
        .Toolbar("bold italic underline subscript superscript | code") // add epi-link anchor if links are needed
        .BlockFormats("");

    config.For<TestBlock>(m => m.Title, limitedRichTextSettings);
});

Problem: Even with these settings, the editor still wraps the content in <p> tags.

Could someone advise on how to properly configure TinyMCE to prevent it from adding these <p> tags in this context?
