Directive @at-root in SASS

The @at-root directive is designed to extract rules from the parent selector to the root of the file.

Let's look at the following example with first-level nesting selectors:

.parent {
	background-color: #fdd;
	@at-root .child {
		border: 1px solid;
	}
}

As a result of compilation we got the following code:

.parent {
	background-color: #fdd;
}
.child {
	border: 1px solid;
}

Now let's look at how the @at-root directive works with multiple selectors:

.main-parent {
	background-color: #fdd;
	@at-root {
		.first-child {
			border: 1px solid;
		}
		.second-child {
			font-weight: bold;
		}
	}
	.step-child {
		color: #232523;
	}
}

After compilation, the code looks like this:

.main-parent {
	background-color: #fdd; 
}

.first-child {
	border: 1px solid; 
}

.second-child {
	font-weight: bold; 
}

.main-parent .step-child {
	color: #232523; 
}

Tell me what the result of compiling the following code will be:

.primary-button {
	background-color: #3272c7;
	@at-root {
		.block-button {
			color: #ff0000;
		}
		.content-button {
			color: #ccb42a;
		}
	}
	.warning-button {
		border: 2px solid #232523;
	}
}
