Freeze when opening doc pages with iframes

[zarunet]

When opening a doc page with iframes in it for the first time (a prime candidate being the iframe page in the HTML docset), Zeal renders the page, then hangs for several minutes before rendering the iframes. Subsequent loads are fine, until the app is restarted.

Just came across this by accident. Earlier today and thought I had to kill the app to have it working again, but it turns out waiting also works.

test-qtwebkit exhibits the same behavior, so apparently it's a Qt WebKit issue. @annulen any ideas?

What could be used as a test page?

I witnessed this issue first on the iframe doc page from the html docset, which is generated from the MDN docs ; so would this one do ?

I had the same issue, however, under preferences if you choose open external link in Zeal it doesn't freeze anymore.
