The docs states:
Similar to modals, only one offcanvas can be shown at a time.

However, I’m able to show more than one offcanvas without any tricks: I created another offcanvas when a list item inside the previous offcanvas is clicked on.

Is this doc obsolete or is it just the browser (Edge) that I’m using? (I haven’t tested on other browsers).

I’m asking to prevent a case of “it works on my machine”.
