I found several steps fail to validate in "Learn HTML by Building a Cat Photo App" course.

This includes so far step nr 19, 20, 21, 22, 26 and probably more.

Validation fails near the closing tag of second section. A fast error message (probably a debug) flashes stating the it couldn't run the test.

When trying different text formatting like putting tags inline it fails the same. Same situation when the auto magic linting is triggered.

This bug prevents completing a step, therefore user needs to navigate back to the course list and manually skip the bugged step.

Tested on latest Chrome, Firefox and Edge with and without adblock.

Attached an example screenshot.
