Callout component doesn't allow for top level class name or fine tuning of its z-index. We have a layering situation where the callout of a background element appears on top of a modal dialog. It should be layered behind the modal dialog but on top of everything else and I don't see an easy way to control the z-ordering of this specific callout without impacting all callouts on the page.
I experimented with doNotLayer but that caused a lot of overflow issues and so didn't seem like a way to work around it.
I also don't want to mess with the z-layering of our modal dialog framework. So this is a feature request to give me a way to be able to specify a layer for this specific callout that places it in-between the two while still allowing callouts that belong to the dialog to appear on top of it.
