Style for embedded editing

You can add css snippet to make the embed content more obvious.

.internal-embed.is-loaded:not(.embedded-part):has(.markdown-source-view):before {
	content: ' ';
	width: 1px;
	position: absolute;
	height: 100%;
	top: 0;
	right: 0;
	background-color: var(--color-accent);
	transition: background-color 200ms ease-in-out, border-color 200ms ease-in-out, opacity 200ms ease-in-out;
}
 
.internal-embed.is-loaded:not(.embedded-part):has(.markdown-source-view):hover:before {
	width: 3px;
	transition: background-color 200ms ease-in-out, border-color 200ms ease-in-out, opacity 200ms ease-in-out;
