[BUG] gridlines borderDash not working for polar/radar chart graphs

[layonferreira]

The option borderDash on gridlines seems to be ignored for polar area charts.
making the grid solid instead.

config:

{
  type: "polarArea",
  data: {
    datasets: [{
        data: [10, 20, 30]
    }],
    labels: [
        'Red',
        'Yellow',
        'Blue'
    ]
	},
  options: {
    scale: {
      gridLines:{
        lineWidth: 2,
        borderDash:[4,5]
      }
    }
  }
}

Doesn't work for Radar graphs either

I am also seeing this issue for radar charts. Is there a workaround?
