The latest shipping version of Edge supports position: sticky and I've successfully tested it with Bootstrap 4 and it works as intended. I added IE10 in place of Edge in that note as I assume that IE10 also has the `position: relative` fallback. REF: https://caniuse.com/#search=sticky

Common values
Quick positioning classes are available, though they are not responsive.
{% highlight html %}
Fixed top
Position an element at the top of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add aditional CSS.
{% highlight html %}
Fixed bottom
Position an element at the bottom of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add aditional CSS.
{% highlight html %}
Sticky top
Position an element at the top of the viewport, from edge to edge, but only after you scroll past it. The .sticky-top utility uses CSS's position: sticky, which isn't fully supported in all browsers.
IE11 and IE10 will render position: sticky as position: relative. As such, we wrap the styles in a @supports query, limiting the stickiness to only browsers that can render it properly.
