mapbox-gl-js version: 1.9.0 mapbox-gl-draw version: 1.1.2

Steps to Trigger Behavior

Initialise draw like:

draw = new MapboxDraw({
  displayControlsDefault: false,
  modes: {
    ...MapboxDraw.modes,
  },
  keybindings: true,
});

2. Create a line feature and select one vertex
3. Press the delete key

Expected Behavior

Vertex is deleted

Actual Behavior

Nothing. You need to have at least the Trash control displayed.
