feGaussianBlur, feOffset and other SVG tags not working in Pyside WebView

Question

Does PySide WebView not support these tags? Or is there anyway to support these tags?

This is my SVG Code. I have made an SVG circle which takes this filter and performs some color transition using javascript

     <defs>
        <filter id="blurr">
            <feGaussianBlur in="SourceAlpha" stdDeviation="1" />
            <feOffset dx="1" dy="1" />
            <feMerge>
                <feMergeNode />
                <feMergeNode in="SourceGraphic" />
            </feMerge>
        </filter>
    </defs>

In PySide, I have made a simple WebView which displays this HTML file.

The HTML file shows the color transition properly in browser but in PySide, It doesn't show any color change.

Answer 1

According to this bug report, filters are not supported and it seems the project has no plans to do so given that the bug has been closed.
