I don't think I can see your attachment, Oliver, but I think the bug may have to do with to these sshots, which both refer to adding a link: in the first one, the recycle bin can barely be seen as it gets hidden, the second one shows the link icon not being displayed as a square. Looks like this can happen both with Chrome and Firefox.

I thinks it depends on the skin: Monobook might be causing this.
That's a different bug - created bug 50057.
This is about CE's rendering of floated templates - I've attached some example screenshots to demonstrate.
For some reason wrapper in which we put transclusions/templates gets HTML attributes of the transclusion/template carried over - including CSS classes - that should not happen, and wasn't happening in the past.
I will investigate it, however adding Roan to this ticket, it seems like it is his area.

Unless the patch hasn't been deployed yet, I guess.
It hasn't. Deployed on Monday alongside the config change. Not sure if the example in comment 17 will be entirely fixed by it though - please check after release?
