Satori treemap labels not being cleaned up on redraw

[mccalluc]

• Specific code commit: 58aa066
• Version of the web browser and OS: MacOS FF
• Environment where the error occurred (Vagrant VM and site conf mode or AWS instance): Test Production

Steps to reproduce

I do not have a reliable reproducer. I saw this after bringing up an old window first thing in the morning, and dragging it between monitors, which seems to prompt a redraw.

Observed behavior

(At first there was only one extra copy of each label, but they seem to be multiplying.

In the console I see this error:

Error: this.children[(this.visibleDepth + 1)] is undefined
i.prototype.removeLevelsOfNodes@https://refinery-static.s3.amazonaws.com/js/commons.js:4:15246

And here's the inner-html of the treemap:

Expected behavior

• Labels should not be repeated.
