I think I found a bug

That’s very possible.

Each line of code has the potential to create multiple bugs, and Lightning has 15.000+ lines of code.

We are very thankful for every report because every bug fix makes the product better.

We have added a feedback form within the product, so you can reach us directly.

Just click the Send Feedback button in the Lightning toolbar (with an assembly open) or click Tools > Lightning > Send feedback.
