Wrong navigator variable scope handling(?)

[KenjiTakahashi]

There happens to be this code in billboard.js:

function convertInputType(mouse: boolean, touch: boolean): "mouse" | "touch" | null {
    const {DocumentTouch, matchMedia, navigator} = window;
    // rest of the code
}

which gets transpiled to:

function convertInputType(mouse, touch) {
  var DocumentTouch = win.DocumentTouch, matchMedia = win.matchMedia, navigator = win.navigator;
  // rest of the code
}

Both of these define a local variable with the name of navigator inside the function.

For some reason, the plugin seems to think that this overrides the global navigator object and stops reporting any compatibility issues related to navigator in the entire project.
