Cannot scroll to the left without triggering backspace

In Chrome and other browsers, two-finger swipe on Mac trackpad by default takes you to the previous page. This prevents you from scrolling left in FigJam, which is highly annoying. But this used to work fine in FigJam—what happened? It still works in Miro, in which it seems to have overridden the two-finger swipe gesture so you can scroll perfectly fine.
