[Bug] Mouse button 5 appears to be displayed as mouse button 3 in recordings

[muzikbike]

Describe the bug
When checking the fix for #1292, I noticed that mouse button 4 is correctly reported as expected, but mouse button 5 uses the middle mouse button colour instead of the mouse 5 colour.

To Reproduce
Steps to reproduce the behavior:

1. Have a mouse with five or more buttons (in this case, a Logitech G402)
2. Click using the fifth button
3. Look at the recorded frames
4. See error

Expected behavior
It'd use the fifth button colour - orange by default.

Screenshots
In order: left, right, middle, fourth, fifth

Desktop (please complete the following information):

• OS: Windows 10
• Version 2.41.0

Additional context
Other programs recognise buttons 4 and 5 fine, so I can confirm the mouse in question is not misconfigured.
