I wasn't sure if this was intended behavior because I can't recall seeing it before. Here's the deal:

I edited the Poll on the wg participate page because the poll didn't seem to be displaying votes. I edited under a tag I didn't want to commit. I created a new tag, called Poll (I think...), and moved my poll edit to it. It moved all revisions of the poll asset ever into that tag. That seemed odd. I wasn't sure if that was supposed to happen, so I just deleted the tag, deleted the poll asset, and created a brand new poll asset.

The odd version tag thing (moving an asset and all revisions appearing) happened on my beta training site too. I've left that out there if anyone needs to see it.
