Can't use "Post Question" button on addon page

I am trying to ask a question about an addon (Rescan All Files) but when I click the Post Question button it throws a javascript error in my console and doesn’t do anything:

main.js:1 Uncaught TypeError: Cannot read properties of null (reading ‘nodeName’)
at M (main.js:1)
at Function.e.fancybox (main.js:1)
at HTMLAnchorElement.onclick (VM361 support:323)

You have to sign-in to the marketplace before that button will work for you.

Thanks you are right. It would be good for usability if the button was replaced with a “Login to Post a Question” button if the user was not signed in.
