[5.0.2] [Moodle 5.1.5] [PHP 8.3] Console error trying to add event listener to non-existing "closebutton"

From the JS console log:

VM830:2 Uncaught TypeError: Cannot read properties of null (reading 'addEventListener')

Looking at the template that is loaded there: https://github.com/grabs/moodle-tool_userdebug/blob/main/templates/debuginfo.mustache

You're looking for #closebutton-{{uniqid}} in there, but you removed the closebutton in the commit: 11f28e0#diff-0e9eb1cbbc938194b3c26f68f50d9ee76718af28c9fbe027b3ed7521c1a0a6a7

Maybe you forgot to also remove or adapt the js in the template?

I would provide a PR but I don't really know for now how it should look like. Currently it looks like this:

Previously there was a pink box with the info. If I remove the collapse class, the box is shown again, above the red bug.

EDIT: Going by your version.php, this plugin version is probably supposed to require Moodle 4.6 at minimum?

Okay, when I remove the mustache JS, everything seems to work, collapse and expand and all.
