(reopen) Exercise Palindrome Products - Automated tests time out (failing).

Closely related to #741 and #759 ?

I solved the [Palindrome Products](https://exercism.org/tracks/typescript/exercises/palindrome-products) in the typescript track.

I encounter what I believe to be timeout on your side. All tests are passing locally, under 20s (the lower value I've been able to reach).

However, the checks on your side are failing with a generic error

>
> **An error occurred**
>
> An error occurred while running your tests. This might mean that there was an issue in our infrastructure, or it might mean that you have something in your code that's causing our systems to break.
>
> Please check your code, and if nothing seems to be wrong, try running the tests again.

Is there anything I can do?

Thanks
