Uncaught TypeError: Cannot read properties of null (reading 'dispatchEvent')

This is looks to be a bug more than something else.

I updated from 5.0.7 to 6.0.0

When I answer to a ticket If I click on “include article” it does not include the article and I get the following in the chrome console:

squished-15638fbe19eb18e3334e2b65f3afd437.js:1

Is there a proper way to report a bug instead of here ?
