RichEditControl - Cursor increases its height when text is typed and Bootstrap styles are registered

I've manually added a RichEdit Control to a Razor page with the following code:

Razor:

@Html.DevExpress().RichEdit(settings =>
{
    settings.Name = "RichEdit";
    settings.CallbackRouteValues = new { Controller = "General", Action = "TestPartial" };
    settings.WorkDirectory = "C:\Temp";
}).GetHtml()

Controller:

public ActionResult Test()
        {
            return View("Test");
        }

public ActionResult TestPartial()
        {
            return PartialView("TestPartial");
        }

While trying to use the extension, the cursor increases in length instead of moving to the right as I type.

In my Layout.cshtml page, I am loading the following Scripts and StyleSheets:

@using DevExpress.Web.Mvc.UI

@Html.DevExpress().GetStyleSheets(
    new StyleSheet { ExtensionSuite = ExtensionSuite.NavigationAndLayout },
    new StyleSheet { ExtensionSuite = ExtensionSuite.Editors },
    new StyleSheet { ExtensionSuite = ExtensionSuite.HtmlEditor },
    new StyleSheet { ExtensionSuite = ExtensionSuite.GridView },
    new StyleSheet { ExtensionSuite = ExtensionSuite.PivotGrid },
    new StyleSheet { ExtensionSuite = ExtensionSuite.Chart },
    new StyleSheet { ExtensionSuite = ExtensionSuite.Report },
    new StyleSheet { ExtensionSuite = ExtensionSuite.Scheduler },
    new StyleSheet { ExtensionSuite = ExtensionSuite.TreeList },
    new StyleSheet { ExtensionSuite = ExtensionSuite.Spreadsheet },
    new StyleSheet { ExtensionSuite = ExtensionSuite.SpellChecker },
    new StyleSheet { ExtensionSuite = ExtensionSuite.Icons },
    new StyleSheet { ExtensionSuite = ExtensionSuite.DashboardViewer },
    new StyleSheet { ExtensionSuite = ExtensionSuite.RichEdit })

@Html.DevExpress().GetScripts(
    new Script { ExtensionSuite = ExtensionSuite.NavigationAndLayout },
    new Script { ExtensionSuite = ExtensionSuite.HtmlEditor },
    new Script { ExtensionSuite = ExtensionSuite.GridView },
    new Script { ExtensionSuite = ExtensionSuite.PivotGrid },
    new Script { ExtensionSuite = ExtensionSuite.Editors },
    new Script { ExtensionSuite = ExtensionSuite.Chart },
    new Script { ExtensionSuite = ExtensionSuite.Report },
    new Script { ExtensionSuite = ExtensionSuite.Scheduler },
    new Script { ExtensionSuite = ExtensionSuite.TreeList },
    new Script { ExtensionSuite = ExtensionSuite.Spreadsheet },
    new Script { ExtensionSuite = ExtensionSuite.SpellChecker },
    new Script { ExtensionSuite = ExtensionSuite.DashboardViewer },
    new Script { ExtensionSuite = ExtensionSuite.RichEdit })

Any idea what the control is behaving so strangely? Does it have some kind of default spacing set or some other issue?
