            Bug ID: 499909
           Summary: Alt and Win Behaviors and Key to Choose 3rd Level
                    incompatible on GNOME applications
    Classification: I don't know

example of settings that will cause this problem

SUMMARY

In System Settings -> Input and Output -> Keyboard, if you set a non english
layout which uses 3rd level, and then in configure key options set both a alt
and win behavior, and a key to choose 3rd level (even if these behaviors should
not be incompatible with each other). You will be able to use this third level
in applications like Kate or Konsole but not applications like Firefox, or
Libreoffice. I believe this is because they are GNOME applications as this
happens in firefox which is running via Wayland.

Note that setting either Key to Choose 3rd Level OR Alt and Win Behaviors, does
cause the behavior to work properly, but setting both causes the key you set to
choose 3rd level to stop working.


STEPS TO REPRODUCE
1. Set your layout to a non english layout
2. go to key bindings, configure key options and enable any alt and win
behavior that won't affect right alt
3. enable any key to choose the 3rd level that should not be incompatible with
an alt and win behavior.

See screenshots for a combination of settings that causes this problem.

OBSERVED RESULT
In software like Kate you can type non english characters from the third level
as expected for these settings. In software like Firefox, you will be unable to
type any characters while pressing this third level button

EXPECTED RESULT
Typing in all programs should be the same.
