Horizontal scrolling using SHIFT modifier stops working when mouse is moved (MacOS + Chrome)

Horizontal scrolling with the SHIFT modifier stops working when the mouse cursor is moved. It seems to invert the SHIFT key, as scrolling will resume working when SHIFT key is released. Until mouse is moved again, at which point it will stop working.

To reproduce

Launch the web version using Chrome on macOS
Open the home menu, and navigate to the "Collections" page
Hold SHIFT and scroll the mouse wheel.
Observe as the list scrolls as expected
With SHIFT still held down, move your mouse cursor 1px or more
Observe as scrolling stops working, even though SHIFT is still pressed
Release SHIFT key and scroll the mouse wheel
Observe as scrolling works even though SHIFT is no longer being pressed
With SHIFT still released, move your mouse again
Observe as scrolling stops working
