My IE does not display the generated TOC or the tasklist entries (you need add a couple of entries into the tasklist to see the issue) in a card. This happens only with the IE. I guess it is something to do with dynamic contents.
You can see the issue in the following simple page:
{composition-setup}
{deck:id=myDeck}
{card:label=tab1}
test tab1 {card}
{card:label=tab2}
{dynamictasklist:test1} {card} {deck}
In my Confluence project page, IE does not display the following {float}{toc} either. It is a simple page with some headers. When I move the mouse-cursor over the area TOC should be drawn I can sense the TOC is really there (the cursor chages and can be clicked to jump to the headers) but the TOC is not displayed or displayed poorly.
{float:right|width=180px|background=#F0F0F0|border=solid navy}
{toc:style=none|outline=true|indent=7px|minLevel=3} {float}
