Triggering an old image caching bug.

[Suges]

Hi and big thanks to Max for creating this project!

In this article Max says to clear out and reload a graph (which is necessary to do if the new graph has some of the same element IDs as the old one), the thing to do is: cy.elements().remove(); cy.add( newEleJsons );.

But I've noticed (at least on the latest versions of Chrome and Safari) doing that seems to trigger this old chestnut of a bug: #1511 (exact same symptoms: only some of the pictures show up; if you click on the node it makes the other show up--but then some of the originals disappear).

You can always fix it by calling something like: const x = cy.json(); cy.json({ elements: x });, but I thought I'd just bring it up here if anyone's interested.

Could you put together a small demo of your issue? There’s a jsbin demo that you can fork to easily put something together http://jsbin.com/fiqugiq

I think I actually just squashed the bug while getting ready to transfer it to jsbin.

I accidentally had two event listeners on my "load a drawing" button; cy.elements().remove(); cy.add( newEleJsons ) was getting triggered twice in rapid succession. Since I removed the second trigger Cytoscape settled right down.

I think we're good here, thanks for your response!
