Using Mod1 as modifier triggers accelerator keys automatically

[Mikaël Francoeur]

1) Release: Ubuntu 16.04.04 LTS

2) Package x11-xkb-utils 7.7+2

3) In xkb, when using Mod1 (bound by default to left Alt and right Alt) to trigger a shift level, typing in a dialog box should not trigger accelerator shortcuts.

4) When using Mod1 in a xkb type, accelerator keys are triggered by default. So when logging in, the "o" in my password triggers the "OK" button, which forces me to use an alternate keyboard layout to enter my password. Same happens, for example, when using the screenshot tool, typing "s" triggers the "Take Screenshot" button.

Attached is the type file causing the issue. The offending type is "SIX_LEVEL", and the issue appears when I use Mod1 as the modifier for any shift level. I don't have this issue on my other layout (us).
