        <pre>After diagnosing the problem and preparing a bug report, I realised that
similar bugs were already submitted (99447, 99534).
However, I'll go ahead and paste/attach my finding, as it might help the
developer further, here is my was-to-be bug report:

[Description]

Simply, when I "tap-to-click" fast enough, everything works as expected,
however, when I tap slowly, it won't register as a click.

See below, it seems as if libinput thinks it is a "click-and-hold".

Note, the slow tap is really not that slow, say sub 200ms, also, the exact
behaviour works under version 1.5.4

Attached is a recordings using evemu to reproduce the behaviour.

[Command I ran]

sudo libinput-debug-events --enable-tap --verbose

[Simplified events]

[[When the tap is missed]]

tap state: TAP_STATE_IDLE → TAP_EVENT_TOUCH → TAP_STATE_TOUCH
tap state: TAP_STATE_TOUCH → TAP_EVENT_TIMEOUT → TAP_STATE_HOLD
tap state: TAP_STATE_HOLD → TAP_EVENT_RELEASE → TAP_STATE_IDLE

[[When the tap is registered]]

tap state: TAP_STATE_IDLE → TAP_EVENT_TOUCH → TAP_STATE_TOUCH
tap state: TAP_STATE_TOUCH → TAP_EVENT_RELEASE → TAP_STATE_TAPPED
 event15  POINTER_BUTTON   +66.16s      BTN_LEFT (272) pressed, seat count: 1
tap state: TAP_STATE_TAPPED → TAP_EVENT_TIMEOUT → TAP_STATE_IDLE
 event15  POINTER_BUTTON   +66.39s      BTN_LEFT (272) released, seat count: 0</pre>
