I can confirm this in Ubuntu 23.10 with a Logitech Gaming Mouse G402 using libratbag to set mouse buttons to 9 and above. Buttons up to and including 8 are recognised, but 9, 10, 11, 12, 13, 14, 15 and 16 don't register at all as the game fails to recognise any input when trying to rebind to this specific button.
evtest confirms that the expected key press event is being sent.
MC-254355's fix resolution implies that mouse buttons 9 and above should be supported.
