Loaded event for sagecell

Hi folks,

I need to call some javascript functions only after a sagecell has been fully loaded on my webpage. I've tried mutation observers and such but nothing is quite right. Does the sagecell emit an event when it has finished doing its thing?

More specifically, I need to resize an outer wrapper-div in the html whenever the sagecell resizes, as it keeps getting cut off. So this would need to work with interacts as well.

I have accomplished this with a plugin for detecting resize events (github) but I'd still be interested if there is a loaded event emited which I could listen to.

There is an official callback event, but in my testing it fires long before the cell is finished processing. If you want to wait until the cell is fully displayed, you'll need to open a websocket to one of the addresses given at the beginning of this document

and then listen for the appropriate response. The document gives sample messages for the entire process of communicating with the cell server, including interacts.
