[IMPORTANT] Left mouse button does not work in Android

Description

Mouse work well on Android and Google TV for apps with native pointer support, like PPSSPP for easy PlayStation Portable emulation setup.

RetroArch lacks a visible mouse pointer on Android, relying instead on scroll-wheel navigation and mouse buttons for menu traversal and configuration. However, the left mouse button fails to register clicks on menu items, preventing direct selection despite scroll and right-click functionality.

Expected behavior

Left mouse button should work.

Actual behavior

Left mouse button does not work. For me it either:

• Didn't work at all
• The menu item activates on mouse down but reverts on mouse up, rendering it unusable.

Steps to reproduce the bug

• Connect a mouse (Bluetooth, or via USB hub) in Android
• Open RetroArch.
• Enable mouse support:
  • Navigate to Settings -> User Interface
  • Toggle Mouse Support on
• Test the mouse
  • Press the right mouse button, it moves one level up in the menu as expected
  • Scroll: It also works as expected
  • Press the left mouse button, it does not behave as expected.
