Observed behavior

We are trying to upgrade to Mirador 4, but the image does not scale well and zooming in is broken.
Working Mirador 3.3.0 instance with the same manifest:

Sandbox with Mirador 4.0.0-alpha.2:
https://codesandbox.io/p/sandbox/mirador-elastic-workspace-forked-l3rwhf?file=%2Fsrc%2Findex.js%3A26%2C94

There are no warnings in the console. Changing the workspace to Elastic seems to fix the image's display, but zooming in or out still doesn't work. Are there changes in the initialization config?

At first glance, this looks like an OpenSeadragon problem. I just tested this with both OpenSeadragon's current master branch and the 2.4.2 version (which Mirador 3.3.0 is built with). The 2.4.2 version seems to work fine, the latest version doesn't.

I'll try to have a look at this in OpenSeadragn myself, but no promises...
