Overview

On touch devices, useLongPress calls onClick twice for one tap.

After touchend, browsers fire emulated mousedown/mouseup (then click) on the same element. The hook attaches both touch and mouse handlers, so the emulated mousedown starts a second press and the emulated mouseup calls onClick again. After a long press from touch, the same emulated events call onClick right after onLongPressEnd.

Repro (Chromium via Playwright with hasTouch/isMobile, page.tap() on a button using useLongPress(onLongPress, { onClick, onLongPressEnd })):

	main	this PR
tap	click, click	click
touch held 700 ms	longPress, longPressEnd, click	longPress, longPressEnd
mouse click	click	click

The event order Chromium dispatches for the tap is touchstart, touchend, mousedown, mouseup, click.

Fix: the hook records the time of the last touchstart/touchend it handled, and a mouse press that starts less than 1 second after that is ignored. Ignoring the mousedown is enough: the following mouseup then finds no pending press and does nothing. Mouse input more than 1 second after a touch works as before, so hybrid touch/mouse devices keep both inputs.

Tests added:

• tap followed by emulated mousedown/mouseup → onClick once (fails on main: called 2 times)
• touch long press followed by emulated mouse events → no onClick (fails on main: called once)
• mouse press 1 second after a touch → handled again

Added a patch changeset.

Checklist

• Did you write the test code?
• Have you run yarn run fix to format and lint the code and docs? (ran yarn lint and prettier --list-different on the changed files; no new warnings)
• Have you run yarn run test:coverage to make sure there is no uncovered line? (100%; test:compiled also passes)
• Did you write the JSDoc? (no public API change, JSDoc unchanged)

Thanks for the contribution!

Could you strengthen one test? In "calls onClick once for a tap followed by emulated mouse events", onLongPress is asserted without advancing the timers, so it passes even if the emulated mousedown starts the long-press timer. Advancing past delay first catches that:

await act(async () => {
  vi.advanceTimersByTime(600);
});

Longer term, Pointer Events seem a better fit than a 1-second window, so I opened #580 for v1. Would you be interested in picking that up as well? The issue has the notes and references.
