Toggling Typewriting Scrolling Using Shortcut Doesn't Work

As the title says. Using the button on the toolbar to turn on and off Typewriting Scrolling works just fine, but trying to do so through keyboard shortcuts doesn’t work; nothing happens. I have tried the original shortcut and I’ve tried changing it, but unfortunately no shortcut I’ve tried, no matter how simple, will work.

Combinations tried:
Meta+Ctrl+T
Ctrl+T
Alt+T
Alt+A
F10

None of those shortcuts were in conflict with any other shortcuts.

I’m using Scrivener Windows v2.9.9.14 Beta (1155038) 64-bit.
