Quiz Start button does not unhide questionset

[ymdahi]

Problem

When a Quiz has Title enabled, clicking on the "Start Quiz" button does not unhide the Questions (.questionset)

Tested on v 1.20.11.

Possible Solution

Consider replace L1035:

h5p-question-set/js/questionset.js

Line 1035 in 9b00511

$('.questionset', $myDom).show();

With:

$('.questionset', $myDom).removeClass('hidden');

Or

let questionRegion = myDom.querySelector('.questionset');
questionRegion.classList.remove('hidden');
