Caman filters not applying to the image until zoom

[joshuastegmaier]

I'm currently attempting to use the demo code, slightly modified, to test out this plugin, and I'm having an issue with all of the Caman filters.

While the non-Caman filters work as expected, the Caman filters don't render on the image until a zoom is performed. This happens even when adding a non-Caman filter after a Caman one--until zoomed, the image is rendered with all of the non-Caman filters, but none of the Caman ones.

Also, only the last Caman filter is applied when rendering, if more than one is selected.

My current code (again, a slightly modified version of the demo code) is here: https://github.com/LibraryOfCongress/concordia/blob/image-filtering/concordia/static/js/image-filtering.js

What could be the cause of this rendering issue?

I'm trying to solve it this way         loadMode: "async",
