Description

The reason for the issue of broken styles for the TextArea component with editors applied when using a Quick Inline Embed link is that if the Quick Inline Embed link includes libs=true property, then a shadowRoot is created to display the form.
At the same time ShadowRoot does not apply external styles. This issue has been fixed for the ace library using the built-in method. However, since the CKeditor and Quill libraries do not support using in ShadowRoot, the appropriate styles were loaded inside shadowRoot to display the TextArea component correctly.

If the Quick Inline Embed link does not include libs=true , then the entire form is displayed as expected.
