The position of suggestions popup is wrongly calculated if the container of the owner component has a scroll bar.
Using getBoundingClientRect inside getPosition(obj) should fix the problem. I'm testing it.
Andrea: I saw you pushed an improvement both in 6.x and master branches. Is there anything more to be done ?
I've tested the issue on all major browsers - Chrome 29, Firefox 23, Opera 12.16, IE 9 and Safari 5.1. The issue is fixed.
thank you! I've forgot to ask you to close it.
ps: can I be granted the right to close an issue?
Yes, I've added you to the Jira "Committers" role, so you should be able.
