Ad not working in WebTester, only after clearing cache.

14:20:53:428 INFO initializing bridge object [object Object]
14:20:52:931 INFO initializing ad frame
14:20:52:923 INFO adWindow loaded
14:20:52:631 INFO creating adWindow
14:20:52:631 INFO rendering

This is as far as the console shows if the ad is run in the webTester
for the first time, or after clearing browser cache. I thought it was
probably happening because of my own ad and code but it when i tried
an Ormma code sample is did the same thing. Basically it shows the
ad, when the ad is clicked, it expands but does not expand past the
50px height.

After an initial run and refresh the webtester works as it should but
my question is really should i worry that my ad will do this in a real
app if it does it in the tester? sorry if this is trivial i only just
started looking into ormma compliance.
