Update: the usage for `hr` was removed in bug 1781102, so it's *almost* unused.

At this point, we only use `-moz-float-edge` as part of the styles for `<math>`:
https://searchfox.org/mozilla-central/rev/02ff1234547a8097df4b07a0deb70dae49ac0d03/layout/mathml/mathml.css#20,33
```
math {
...
  -moz-float-edge: margin-box;
```

Maybe we could remove that as part of modernizing some of our mathml stuff, though. I know Igalia folks have done a lot of standardization work on defining how MathML behaves over the past few years, and it wouldn't surprise me if they managed to standardize it such that this is no longer necessary.
