Im- / Export Configuration does not save Mouse Modifiers

[Sebadier]

Hi,
I have a special set of key bindings and mouse modifiers for certain editing tasks and I want to be able to import them from a config file and not assign them manually every time.

The import configuration seems to be buggy though.
What I did:
- adjusted all key bindings and mouse modifiers to taste
- saved the configuration with "export configuration" action selecting "cursor and keymaps" and "action and key bindings"
- changed configuration for other tasks
- imported configuration with "import configuration" action.
-> keybinding are fine, mouse modifiers are on default.

Is this a bug or am I doing something wrong here?
