1756801 - can trigger history swipe without arrow/animation showing

Status: RESOLVED FIXED

(Core :: Panning and Zooming, defect, P3)

Description

[Timothy Nikkel (:tnikkel)]

This is on macOS, haven't tried on Windows yet.

Swipe sideways until the arrow is 100% opaque indicating a history navigation would happen if you lifted your fingers, then swipe back just enough to lower the opacity below 100% and lift you fingers. Then swipe sideways again far enough to trigger the history navigation and lift your fingers. Maybe 33% of the time when I do this I can trigger a history navigation without seeing the arrows/animation.

Tested on latest nightly.

Marking as S3 for a behaviour that has been shipping on macOS for a long time.

If this is reproducible on Windows, we can consider separately if this should block releasing the feature there.
