How to get hovering to work in PyQt

Hi there. I wrote some PyQt tools that embed pygal grpahs, and I've been scratching my head trying to solve this issue:
I am using QWebView to display rendered svg files. So far, I can get the svg to show up correctly, but tooltip and hovering does not work (I can check on and off on the legend though). The same svg renders fine in browsers. I was wondering if there's any additional javascript I need to include in my svg file with the one found in https://github.com/Kozea/pygal.js/tree/gh-pages/2.0.x/

Any help is much appreciated!

Start by comparing the SVG behavior in PyQt's QWebView with the same rendered SVG in a browser, then inspect the pygal.js 2.0.x files linked in the issue. Confirm whether the tooltip and hover behavior depends on JavaScript that QWebView is not loading; done means identifying the required setup or documenting that limitation.
