Js-ipfs unit tests failing

I’m interested in working with js-ipfs, and I’m trying to run the unit tests. I’m following these docs but I’m having an issue with chromium:

ipfs-core-utils: Test Browser

Could this be an environment issue? Or any idea what could cause this?

I’m running on Lubuntu 20.10 with Node version 14.16.1.
