JavaScript error on create AB test page

[vdboor]

On creating the AB test, the following error happens:

wagtail-ab-testing.js?v=afb7bfd0:2 Uncaught ReferenceError: abTestingTabProps is not defined
    at HTMLDocument.<anonymous> (wagtail-ab-testing.js?v=afb7bfd0:2:397058)

I'm running Wagtail 6.0.5, wagtail-ab-testing 0.10 on Python 5.0.7, Python 3.10

Edit: I just checked, and it seems the script is only needed for the actual edit page?
As the main script is also loaded on /cms/abtests/add/##/ it gives this error as no action menu is there.

I am seeing this same error. In addition, when I try to select the page for the test I get the following error:

In addition, when I try to select the page for the test I get the following error:

This is a separate issue, which should be fixed by #85.
