Chart.js pie chart in table shows weird behavior on page resize

Question

There are chart.js pie charts in a html table. The issue: on zoom-out and then zoom-in, the cells do not resize to their initial size. The layout looks something like this:

 __________________________
|   inner div | inner div  |
|_____________|____________|
|             |            |
|  Pie1       |  Pie2      |
|_____________|____________|

I have referred the documentation on resizing and this link to add responsive and maintainAspectRatio fields in options object.
On setting responsive:true, the diagram is enabled to resize on zoom.
Setting maintainAspectRatio:false, to fix previous irregular zoom issue where the multiple charts do not resize proportionally since they take table cell's width.
Just for reference there is a blurry text issue with chart.js zoom mentioned at github here.

Sourcecode of issue on JS fiddle: http://jsfiddle.net/rfaLvuho/.
Use zoom-out and zoom-in back to reproduce.

You can switch to <div> elements for the layout to fix this. I used float in the snippet below but it should work with flex or grid layout as well.

var randomScalingFactor = function() {
  return Math.round(Math.random() * 100);
};

chartColors = {
  red: 'rgb(255, 99, 132)',
  orange: 'rgb(255, 159, 64)',
  yellow: 'rgb(255, 205, 86)',
  green: 'rgb(75, 192, 192)',
  blue: 'rgb(54, 162, 235)',
  purple: 'rgb(153, 102, 255)',
  grey: 'rgb(201, 203, 207)'
};
var config = {
  type: 'pie',
  data: {
    datasets: [{
      data: [
        randomScalingFactor(),
        randomScalingFactor(),
        randomScalingFactor(),
        randomScalingFactor(),
        randomScalingFactor(),
      ],
      backgroundColor: [
        chartColors.red,
        chartColors.orange,
        chartColors.yellow,
        chartColors.green,
        chartColors.blue,
      ],
      label: 'Dataset 1'
    }],
    labels: [
      'Red',
      'Orange',
      'Yellow',
      'Green',
      'Blue'
    ]
  },
  options: {
    responsive: true,
    maintainAspectRatio: false,
    legend: false
  }
};

var myPie1 = new Chart('chart-area1', config);
var myPie2 = new Chart('chart-area2', config);

.canvas-holder {
  width: 50%;
  float: left;
}
