A heads-up on my ongoing investigation of the issue: packages built from
trunk (tested on 2013-03-28) work well, i.e. pages start rendering while
still loading, whereas packages built from the latest release branch
(git://gitorious.org/qt/qtwebkit.git, being prepared for 5.1.0) still
exhibit the issue, i.e. pages are not rendered until fully loaded.
So the problem persists in 5.0.1 and above, but has somehow been fixed
in trunk. If I read the history of the release branch correctly, the
latest import from trunk was revision
6a4a1d32e1d779548c726c4826cba9d69eb87601 (svn 136242), on 2012-11-30.
Which makes me think that the issue (regression?) was fixed sometime
between 2012-11-30 and 2013-03-28 in trunk (roughly 10000 commits).
Any hint where I should be looking for what possibly fixed the issue?
Do others observe the same issue with 5.0.1?
