Billboard.js: Grouped selection with multiple: false throws error

[thektan]

Description

Passing the following configs causes an error:

data: {
      selection: {
        enabled: true,
        grouped: true,
        multiple: false
      }
}

Error after clicking on a point:

Uncaught DOMException: Failed to execute 'querySelectorAll' on 'Element': '..bb-shapes-data1' is not a valid selector.

Seems like an additional . is added causing an invalid selector.

Steps to check or reproduce

Click on one of the points in the example below. Observe the console.
