Runeglaive + Iceborn( and other sheen items ? )

So as people are starting to notice, there are quite a few bugs on the runeglaive. From what I gathered from the other threads: http://boards.na.leagueoflegends.com/en/c/bug-report/osv4p999-gameplay-ezreal-runeglaiveiceborn-glitch http://boards.na.leagueoflegends.com/en/c/bug-report/cAVEsrQx-skarner-runeglaive-bug

There is something unclear right now as to how sheen items are supposed to work. Because same name techniques usually do not both work but we already know that you usually can add the iceborn to trinity and you'll have the slow field at least.

But here I doubt it's wanted since both passives are aoe. I tested it on gp and it works only with the Q when you're in auto attack range( but it works everytime ). It seems it works just all the time on skarn, and the ezreal q also does it sometimes when the range isn't very high.

I think i'll go test it out on Ezreal and land Q's in melee range.

anyway, this looks like a bug.
