Cannot Swipe to Navigate when UIPageLayout Contains ScrollingFrame

When it started happening: 2020-04-13T01:07:00Z
Possibly before now, but I’ve only just noticed it.

Description of bug
When a UIPageLayout has a ScrollingFrame as its sibling, the user cannot swipe to navigate between pages when swiping over the ScrollingFrame.

I have attached a video of the bug captured from my phone. It also occurs in Studio using the emulator. My “pages” consist of only ScrollingFrames (which in turn also have ScrollingFrames as their descendants, to form the collapsible-sections). The ScrollingFrames are only scrollable on the Y-axis. As you can see from the video, it somewhat registers a swipe and the next page peeks out, but it doesn’t actually move between pages.
