Question preview submit does not work in moodle 4

[mputzi]

When previewing a question of qtype_geogebra in moodle 4 (tested on 4.0.1+, 2022041901.02) with an authoring role a click on button "Check"or on "Submit and finish" has no effect: No reload is being triggered. There is no warning or error on the console.
In a quiz activity the questions are evaluated correctly.

Substituting

moodle-qtype_geogebra/amd/src/ggbq.js

Line 139 in d6a19fe

$('#responseform').on('submit', this.getBase64andCheck);

with
document.getElementById('responseform').addEventListener('submit', this.getBase64andCheck);
the submitting works.

Apparently there is some jquery magic going on interrupting the submitting itself.

Also tested in student's view: Seems to work here, too. Can you confirm @mputzi?

Sorry, I have bad news:
Submitting works now and submit triggers a site reload, but something is wrong with the returnurl: I am getting an error type 403: Forbidden.
The URL when reload is triggered is:
https://mytestserver.de/question/bank/previewquestion/preview.php?id=2&previewid=9&cmid=5&returnurl=https%3A%2F%2Fmytestserver.de%2Fquestion%2Fedit.php%3Fcmid%3D5%26amp%3Bcat%3D2%252C16&variant=1&correctness=1&marks=2&markdp=2&feedback=1&generalfeedback=1&rightanswer=1&history=0
tested on moodle 4.1dev (Build: 20220527)

Just tried all possible ways again, cannot trigger a 403 in my dev environment (current MOODLE_400_STABLE with latest master of qtype_geogebra). Sure, this is not a "switched to student role in another tab before hitting the button" or anything like that? :-) Could you pls share a backup file of an example quiz you were able to trigger this error with?

EDIT: Also just updated to current core master, also works, no 403
