Upgrading from v2 to v3 - tracked issues?

My 3.16 app has been running v2.0.13 for some time, tried to upgrade to v3 but having some problems. Once on any v3 version, the dropdown content no longer opens or appears

Tested a few versions;

3.0.11 broken :red_circle:
3.0.7 broken :red_circle:
- tested this one specifically, because it was the version before ember-maybe-in-element was updated. I suspected a conflict between versions of this package and some of our other packages - no longer think this is the case
3.0.0-beta.1 broken :red_circle:
- this update introduced glimmer components
2.0.15 works :green_circle:
2.0.13 works :green_circle: (what we use currently)

Based on my research;

the trigger is clicked successfully
basic-dropdown.ts -> toggle() is called, this.publicAPI.isOpen is correctly read and successfully calls the correct open()/close()
open/close both correctly set isOpen to true or false, so that the next toggle() correctly reads a new this.publicAPI.isOpen value all good so far

I added the following to the basic-dropdown.hbs template..

{{log "basic dropdown testing"}} // prints as expected
{{log this.publicAPI}} // never changes
{{log this.publicAPI.isOpen}} // never changes
{{log this.isOpen}} // changes between true/false as expected, when trigger is clicked

If I then follow the trail, this.publicAPI.isOpen is what is read in the content component, and https://github.com/cibernox/ember-basic-dropdown/blob/4596ed5475c47f90038dad44dd11c0dac6e34d12/addon/templates/components/basic-dropdown.hbs#L16 https://github.com/cibernox/ember-basic-dropdown/blob/4596ed5475c47f90038dad44dd11c0dac6e34d12/addon/templates/components/basic-dropdown-content.hbs#L2-L4 Sure enough, I always see the content-placeholder element, it's never replaced by the origin-wormhole element above. https://github.com/cibernox/ember-basic-dropdown/blob/4596ed5475c47f90038dad44dd11c0dac6e34d12/addon/templates/components/basic-dropdown-content.hbs#L33-L35

I'm a little bit new to this glimmer stuff, but is there anything I could be missing as to why this.publicAPI and this.publicAPI.isOpen is never updated in the template?
