Why does Container work so strange???

Hello

I have MyVideoNav opened with some contents displayed.
I open a custom dialog from MyVideoNav, and it contains a wraplist inside a group inside a list.
In this wraplist I have (this is my own plugin, so only syntax matters in this case)

Code:
<content>plugin://plugin.stiff?path=$INFO[Container.FolderPath]&fetch=genres</content>

The $INFO part works, fetching FolderPath of main MyVideoNav container (ie. the currently displayed <views> item)

Why is it like thatConfused Accidentally this is what I want, but I really don’t like magic like that, as it can stop working any moment. I suspect Container item has some special meaning, as opposed to Container(id) which refers to a specific container.

So far communication between windows was possible for me only with Properties, as there is no way to reference another window in info (even something like like Window(videos).Container.FolderPath doesn’t work in the above example).
