Draftail not showing entity buttons.

[webquest-nz]

Issue Summary

I created this issue on stack overflow and no solutions.

The Wagtail example of using entities as given in this page of documentation isn't working for me. I am following the third example of using Entities which is supposed to create a button for stock price but no button is appearing for me in the rich text field in the admin editor. I have created a minimum reproducible example which demonstrates just this problem. https://github.com/kiwiheretic/stockentity. I am using Wagtail 4.1.1 which I understand is the latest version.

Steps to Reproduce

Using wagtail 4.1.1 follow the instructions for StockEntity as per https://docs.wagtail.org/en/stable/extending/extending_draftail.html#creating-new-entities. Also GitHub repository above.

Any other relevant information. For example, why do you consider this a bug and what did you expect to happen instead?

Expected to see a stock button draftail editor. No such button appeared

Following that tutorial requires highlighting empty text in order for the option to appear (see #9281 )

I suspect this was likely the same issue as #9281, as far as I can see the stock button works as expected.
