Problem with blockquote

I am using Summernote 0.8.20 Windows 11 64bit system Google Chrome browser

In the text within the editor, when applying a quote to a text, it remains the same without any indication that it has a blockquote applied.

Furthermore, the styles do not appear in the editor menu; for example, "quote" does not appear with the bar on the right, even though the page has the following styles applied:

body.page blockquote {
	border-left: 5px solid #f86466;
	background: white;
}
