External mouse and keyboard on MCPE do not work as expected

LG Nexus 5x

Have connected Bluetooth mouse and keyboard to my phone and these issues occur when playing:

• Holding down space does not continuously jump
• You have to click and drag to move your head/camera rather than just moving the mouse
• Left, Right, and Middle click work correctly but after some delay
• Scrolling does not change your hotbar slot

Will edit with video when I have time to record the behavior.
