[Bug 23363] requestFullscreen and dialog.showModal interaction

https://www.w3.org/Bugs/Public/show_bug.cgi?id=23363

--- Comment #2 from Matt Falkenhagen <falken@chromium.org> ---
I guess what's not defined is what "add an element to the top layer" means when
it's already in the top layer. Is it moved to the top of the top layer, remain
where it is, or do you have two copies in the top layer?

For example, the HTML spec says:
"When an element is added to the pending dialog stack, it must also be added to
the top layer layer."

And requestFullscreen says:
"add context object on document's fullscreen element stack", which leads to:
"To add an element on a document's fullscreen element stack, add it on top of
document's browsing context's top layer[...]"

In these cases, what do you do if it's already in the top layer?

Maybe I'm just reading too much into the word "add"... is the behavior actually
well-defined here?
