Steps to reproduce the issue

See video recording - keyboard navigation only - all key presses highlighted on screen by external software
Creating seperate issue for each bug report so that they dont get lost inside a bigger report (again)

If a field is required you can not move forward in the tour until you complete the field ✔️
But if you then go back you have to enter something in the field again even though iy is not empty ?
So obviously something wrong in the code to check the field has input

The requirement to use a mouse to successfully use the Guided Tours component is an accessibility failure and breaks our commitment to providing an accessible way to use Joomla
