seems it's because of 100% height in div. try to use some px value.
Tried it with / without the div. Also set to 800px / 800px.
Still no difference.
ok.. Do you able to share the war somewhere? I've just put the same page to demosite environment(under nightly 3.3.1) and still have the normal behavior. Or at list share screenshot please.
Yes, such problem was detected before GA and caused by prototype update before release. But according to my info was fixed :/
Could you please check under 3.3.1 snapshot? And if you able to provide the war and its reproducible under snapshot - please just rise the issue in our jira and put the links there and in jira.
