This variable overrides history user data, which makes the current
article and position restoring code in ArticleView::loadFinished()
difficult to understand.
Encode the same logic in the history user data instead. This should make
the code more straightforward and less brittle in the face of changes.
MainWindow calls ArticleView::reload() when the group list is updated.
This updating may add/remove/reorder dictionaries in the active group.
MainWindow also calls ArticleView::reload() when the display or addon
style changes.
In both of the above scenarios uncontrolled jumps and current article
change can occur (see also the parent commit message).
Move setting articleToJump from above the only ArticleView's reload()
call into ArticleView::reload() itself.
This way it is clearer that the pages history is updated just before
each navigation to a different page.
The call to ArticleView::saveHistoryUserData() now occurs slightly later
in ArticleView::showDefinition(). I don't think the intervening code can
affect the current article or window position. So the reordering most
likely does not affect application behavior.

Qt WebKit Bridge documentation recommends:
When exposing native objects to an open web environment, it is
important to understand the security implications. Think whether the
exposed object enables the web environment access things that
shouldn't be open, and whether the web content loaded by that web page
comes from a trusted source.
The author of Qt WebChannel has said the following in a talk that
introduced this Qt module (WebKit Bridge replacement for Qt WebEngine):
My suggestion here is to write dedicated QObjects with a slim, minimal
API that only have the signals and methods that you deem safe to be
used from the outside.

When the current article is set and the user expands or collapses
optional parts (e.g. via the Ctrl+* shortcut),
ArticleView::setCurrentArticle() is called twice from
ArticleView::loadFinished(). Furthermore, the window scroll position is
restored before the second jump. This is wasteful. Move the
higher-priority setCurrentArticle() call up and, if it succeeds, skip
the other call and the scrolling.
I have measured the time spent running the affected code fragment on my
GNU/Linux system before and at this commit. When the loaded articles are
not very large, the performance gain of this commit is only about 1 ms.
However, when one of the displayed articles was huge (the
"United States" English Wikipedia article), the time went from 120 ms to
5 ms.
Extracting this function allows to simplify the code and facilitates
optimizing it in the next commit.
Remove `#if QT_VERSION >= 0x040600` along the way as GoldenDict does not
support Qt versions older than 4.6 for several years now.
