I've been trying to make sense of this bug for the past day or so. I've been
able to narrow down the problem a bit, but can't pinpoint it exactly because
I'm a QT novice.

In the first browser instance, resizing works until the first page is loaded.
This can be tested by commenting out the m_browser->setUrl() in the function
WebBrowser::graphicsWidget() in webbrowser.cpp, or simply severing the internet
connection before starting the applet.

After the page is loaded, none of the children of the applet receive
setGeometry() signals and do not resize accordingly. It seems as if the main
layout of the widget gets disconnected from resize events.

The problem appears somewhere between the call to WebView::setUrl() in
webview.cpp (kdelibs/plasma/widgets/), which only contains a call to
QWebFrame::load(), and before the page is loaded (before
WebViewPrivate::loadingFinished() is called).

I tried a workaround by creating a WebBrowser::constraintsEvent() handler which
calls m_layout->setGeometry(contentsRect()). This results in resize working,
but margins are not preserved and it doesn't fix the underlying problem.
