Bug#385355: "altwin:meta_win" overrides "lv3:lalt_switch"

[Ben Mueller <bmueller@uni-math.gwdg.de>]

Package: xkb-data
Version: 0.8-8

This bug is very similar to #276143 (merged with #281398). But neither the 
proposed workaround nor the submitted patch do help in this case.

I want to use
  XkbOptions "altwin:meta_win,lv3:lalt_switch"
to make the left Alt key the 3rd level chooser and to map Meta to the win 
keys. But the option "lv3:lalt_switch" is cancelled by "altwin:meta_win" 
no matter in which order the options are listed.

The problem appears also in earlier versions of the package.
