Log of changing keymappings with a fresh wineprefix

Hello Wine dev team,

I tried launching MotoGP 2 (verified that the demo also has this issue) and
found out that

- after the game is installed and
- started via launcher.exe and
- the launcher appears and
- clicking the "Configure controllers" button and
- changing a key mapping, byselect a key listed in the right panel, then double
click a function in the left panel and
- closing the controller menu by clicking on OK and
- reopening the controller menu (like in one of the previous steps), then the
previously changed mapping is not present anymore (like no change to the key
has been made)

I expect that changed key mappings are persistent after setting it up and
confirming the controller configuration menu and after closing and starting the
game.

Important note: When having an empty wineprefix (deleted wineprefix folder) the
first change of a key map is persistent, even when closing the game. The
changes made after that change will not be persistent.
This was tested with the key "Escape" and it was set To "Accelerate" for
testing purposes.

This works on a recent Windows 10 (when using Microsoft DirectInput Mapper).
See the following comment: https://bugs.winehq.org/show_bug.cgi?id=52198#c14
why MS DirectInput Mapper is not used here.

I was able to log messages from wine and added them as attachment.

Fixing this might be too much work: See comment 14:
