// A stale APZ touch count after preventDefault() on touchmove can leave the
// long-press timer running for a gesture on a different APZC, firing contextmenu
// after the finger lifts. This test reproduces this bug.
//
// Repeat in another tab to use a different APZC. A stale touch count makes APZ
// reset the previous APZC and mark the new touch block as already reset. This
// skips the reset needed to cancel the new long-press timer when touchmove is
// prevented, causing contextmenu to fire after the finger is lifted.
//
// Add the touchmove listener during touchstart so APZ processes touchstart before
// waiting for the page's response to the first touchmove. If we add the touchmove
// listener before touchstart, APZ may also delay processing touchstart until the
// page responds. Then, preventing touchmove could drop touchstart before it
// increments the touch count, so the bug would not reproduce.
