[minor bug] [minor FR] Collapse-Node compatibility

[Pixel3ro]

i use this Collapse-Node plugin to fold-unfold cards in my canvas. When a Portal is double clicked upon, when it's card is folded, it wont open.

Collapse-Node is a very handy plugin, and I believe it should be integrated into Advanced Canvas. the plugin is not in active development, and has issues like not recognizing overlapping cards, etc. which leads to a clutter. and the irony is, this plugin's sole job is to help with managing clutter. it'd be a great addition to the suite of tools in Advanced Canvas. Please consider it.
