I found this older issue : https://github.com/driftyco/ionic/issues/1866 that describe exactly my problem (at least it looks like it), but while having similar issue I wonder if this was already fixed ?
I am using Beta #13 and still seeing this behaviour.
I do not really have a codepen example, but I would be able to provide to the Team the ID # for the Ionic view App where you could see the actual behaviour.
This seems to be also related: Collection-repeat + ion-infinite-scroll performances on beta 13
Thanks for any guidance you can provide,
