15.0-RELEASE without/with p1: I2C Touchpad of My Laptop doesn't work well

Kernel booting messages about the I2C touchpad:

iichid0: <FTCS0038:01 2808:0106 I2C HID device> at addr 0x38 on iicbus15
iichid0: Using sampling mode

hms0: <FTCS0038:01 2808:0106 Mouse> on hidbus0
hms0: 2 buttons and [XYW] coordinates ID=1
hmt0: <FTCS0038:01 2808:0106 TouchPad> on hidbus0
hconf0: <FTCS0038:01 2808:0106 Configuration> on hidbus0
hmt0: Multitouch touchpad with 0 external buttons, click-pad
hmt0: 5 contacts with [C] properties. Report range [0:0] - [1481:911]

I used "libinput debug-events" to dump all captured input events.

Under FreeBSD 14.3-RELEASE, the touchpad works well.

Under FreeBSD 15.0-RELEASE (without p1), few input events of the touchpad can be shown.

Under FreeBSD 15.0-RELEASE p1, some input events of the touchpad can be shown. But most of gesture events are lost.
