<pre>Moving this from a downstream bug report:
<a href="https://bugzilla.gnome.org/show_bug.cgi?id=777479">https://bugzilla.gnome.org/show_bug.cgi?id=777479</a>
Evolution uses frame flattening and shows messages in iframe-s. Having frame flattening enabled and this top web page:
<html>
<body>
<iframe style="height:10px" src="file:///tmp/a.html">
</body>
</html>
and the /tmp/a.html being
<html style="overflow:auto;">
<body style="height:100%;overflow:auto;">

</html>
causes the iframe being only 10 pixels height and the content being scrollable (with scroll bars). The downstream bug report has a screen shot of it.
Changing /tmp/a.html body's style to not include height:100% fixes the issue and the iframe is expanded based on its content.
I have a standalone application which uses pure WebKitGTK+ exposing this issue. I can share it, if it would be useful for you.</pre>
