Picture not enlarging on front end in a Lesson

Hi there!

I was adding pictures in one of the lessons of the course.

I used the block editor, and set it to enlarge the picture when clicking on it.

When checking the course on the front end, the lightbox does not appear. The pointer shows the magnifying glass icon and also the little icon on the top right corner. Just, it does not do anything when clicking on it.

I asked a friend of mine, and after checking, he has the same problem.

I do believe it's a bug, did any of you encountered the same problem?

Thanks in advance for thinking along! ☀️
