I have the same issue! All tests including random tests passes. But not the fixed test "Second long text block". Really strange.

got the same error im kind of frustrated as it took me a lot to use map() and flat() and now this?? My theory is that it has a lot of special characters. But the thing is i cant even read this without getting dizzy.

такая же проблема.

"(123) 456-7890"  => true
"(098) 123 4567"  => false
          ^
   what's missing there?
