Summary: Tracked component catches rejected promises under it to log them. After catching promises become "handled". This might hide potential promise error handling mistakes, so it's better to ensure we keep promises unhandled after catching them for tracking, so they are properly catched by the unhandled promise handler after that. The easiest solution seems to just make new rejected promise and return it instead of the catched one.
