Quality Assurance Projects - Sudoku Solver - Bug in the example?

Tell us what’s happening:
At the beginning of each project, and example of a successfully-completed project is given. The Sudoku Solver example is here: https://sudoku-solver.freecodecamp.rocks/

However, when trying to see how it responds to various types of invalid input, I noticed that it will provide a “solution” to the following input, which should result in an error:


It ends up with a solution that has two 9s in the top row, two 9s in the top-left 3x3 grid, and two 9s in the second column.

Is this a bug that should be reported somewhere? If so, where and how should it be reported?
