Fixes #30503

The navbars still seems to be broken: https://deploy-preview-30505--twbs-bootstrap.netlify.com/docs/4.4/components/navbar/

I think we better use the .fixed-top class here? I also spotted some margin hacks, I think we can get rid of them too:

bootstrap/site/docs/4.4/assets/scss/_component-examples.scss

Lines 222 to 242 in 93d745e

	.bd-example {
	.fixed-top,
	.sticky-top {
	position: static;
	margin: -1rem -1rem 1rem;
	}
	.fixed-bottom {
	position: static;
	margin: 1rem -1rem -1rem;
	}
	@include media-breakpoint-up(sm) {
	.fixed-top,
	.sticky-top {
	margin: -1.5rem -1.5rem 1rem;
	}
	.fixed-bottom {
	margin: 1rem -1.5rem -1.5rem;
	}
	}
	}

@mdo friendly ping 🙂 BTW this doesn't seem to apply to master, right?

Indeed! Updated to use .fixed-top and nuked the .position-fixed override styles.

Nope, pos-f-t doesn't seem to be present anymore
