### Beta/Release Uplift Approval Request
* **User impact if declined**: On some pages, scrolling via touchpad can sometimes get stuck in a position where you can't scroll further even though there is room.

This has so far only been observed on certain pages where you're pinch-zoomed in, but could in principle affect other pages we're not aware of.
* **Is this code covered by automated tests?**: Yes
* **Has the fix been verified in Nightly?**: Yes
* **Needs manual test from QE?**: No
* **If yes, steps to reproduce**: 
* **List of other uplifts needed**: None
* **Risk to taking this patch**: Low
* **Why is the change risky/not risky? (and alternatives if risky)**: Especially if uplifted together with bug 1787099, this patch moves the relevant code areas in a direction of greater consistency (in the units we use to make comparisons like "are we close to the edge"), and regressions such as this one have been caused by lack of consistency.
* **String changes made/needed**: 
* **Is Android affected?**: No
