Actually, it looks like this is a regression which was introduced by bf3e8502eefd ("Input: synaptics-rmi4 - clean up F30 implementation"). From the bug report I noticed that the INPUT_PROP_BUTTONPAD property was not set for the touchpad. The previous behavior was to set INPUT_PROP_BUTTONPAD if F30 detected only one valid button (or if there was a flag in the platform data). But, now INPUT_PROP_BUTTONPAD is not being set and libinput does not know that the touchpad is a clickpad. After updating I was able to reproduce the issue with bf3e8502eefd applied.
