Modifiers can erroneously end up perma-set #583
Description
Consider the following symbols file (reduced from a real-world example):
default partial alphanumeric_keys
xkb_symbols "base" {
name[Group1] = "Test latching behavior";
key <AB01> { [ z, Z, y, Y, ezh, EZH, ydiaeresis, Ydiaeresis ], type[Group1] = "EIGHT_LEVEL" };
key <LCTL> { [ Control_L ] };
key <RALT> {
symbols[Group1] = [ ISO_Level3_Latch, ISO_Level5_Latch ],
actions[Group1] = [ LatchMods(modifiers=LevelThree,latchToLock=false,clearLocks), LatchMods(modifiers=LevelFive,latchToLock=false,clearLocks) ],
type[Group1] = "PC_CONTROL_LEVEL2"
};
};
When used along with the standard xkeyboard-config data, under current xkbcommon, with the following sequence of keypresses:
- Press
<LCTL> - Press and release
<RALT> - Release
<LCTL> - Press and release
<RALT> - Press and release
<AB01>(this should unlatchLevelThree)
LevelThree (Mod5) ends up permanently set, with no way to clear it, making the keyboard unusable.
