<img> tag in QML Text isn't smoothly scaled

Please see poorImageQuality.png attached and compare:

Text{
    text: '<img src="BarChart.png">'
    scale: 1.1
}

with

Image{
    source: 'BarChart.png'
    scale: 1.1
}

Scaled Image quality in Text is poor. Setting Image::smooth: false causes similar behavior, but there appears to be no way to turn smooth on in Text. Perhaps Item::smooth (which defaults true) could be used to turn on/off?

I'm on Windows and haven't tested other platforms. BarChart.png is attached.
