I debugged the code to got the points that are drawn to the canvas.
```javascript
const canvas = document.getElementById('canvas')
const ctx = canvas.getContext('2d')
const points = [
[300, 300],
[196.0769515458674, 239.99999999999994],
[300, 300],
[299.99999999999994, 390],
[403.92304845413264, 360.0000],
[300, 300],
[300, 300],
]
ctx.beginPath()
ctx.moveTo(points[0][0], points[0][1])
ctx.lineTo(points[1][0], points[1][1])
ctx.lineTo(points[2][0], points[2][1])
ctx.lineTo(points[3][0], points[3][1])
ctx.lineTo(points[4][0], points[4][1])
ctx.lineTo(points[5][0], points[5][1])
ctx.lineTo(points[6][0], points[6][1])
ctx.closePath()
ctx.fillStyle = 'red'
ctx.fill()
```

It does seem to be a Chrome bug?
