Migaku Extension doesn't show anything on load

Steps to reproduce:

make a free/trial Migaku account
install immerse with Migaku extension
log in with a Migaku account after installing it
see that when clicking on the icon, instead of showing the setup flow it just ends up all white.

Expected behavior:
Be able to set up this extension on Orion.

Orion, OS version; hardware type:
Version 0.99.114.1-beta (WebKit 614.1.12), Mac M1 Pro 16", Monterey 12.2.1

Image/Video:

Still is the case as of Version 0.99.125.3-rc (WebKit 616.1.22)

Still the case with version 1.3.18 (6) (WebKit 8620.2.4.10.8) it seems. In my case, the extension is installed, but won’t allow me to log in.

I have the same issue, the extension installs but the Log In button does nothing.

Orion Version 0.99.133-beta (WebKit 621.1.2.111.4)
