Ignore keyboard layout doesn't work with non-standard English layout

For example I have English (Colemak) and Russian (standard)

In VimFx I used this settings:

vimfx.set('translations', {
  // Colemak mappings.
    "KeyE": ["f", "F"],
    "KeyR": ["p", "P"],
    "KeyT": ["g", "G"],
    "KeyY": ["j", "J"],
    "KeyU": ["l", "L"],
    "KeyI": ["u", "U"],
    "KeyO": ["y", "Y"],
    "KeyP": [";", ":"],
    "KeyS": ["r", "R"],
    "KeyD": ["s", "S"],
    "KeyF": ["t", "T"],
    "KeyG": ["d", "D"],
    "KeyJ": ["n", "N"],
    "KeyK": ["e", "E"],
    "KeyL": ["i", "I"],
    "Semicolon": ["o", "O"],
    "KeyN": ["k", "K"],

    "CapsLock":    "Backspace"
});

No file, test, or entry point is named. Reproduce the issue with English Colemak and Russian standard layouts, then trace how keyboard events and the VimFx translations setting are handled; done means the configured mappings work correctly with the non-standard English layout.
