Bug ID: 167198
Summary: [GTK] height:100% breaks frame-flattening
Classification: Unclassified
Product: WebKit
Version: WebKit Local Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebKit Gtk
Assignee: webkit-unassigned at lists.webkit.org
Reporter: mcrha at redhat.com
CC: bugs-noreply at webkitgtk.org
Moving this from a downstream bug report:

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;">

</body>
</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.
