predicts method is stuck when trying to predict geostationary sattelites

[olesh0]

We all know that it doesn't make sense predicting geostationary sattelites, but we I run jspredict.transits() it's just stuck without any response.

Example sat:

TIANTONG-1 3
1 47321U 21003A 21043.86080390 -.00000167 00000-0 00000-0 0 9992
2 47321 5.4820 309.9001 0001441 344.5940 240.0923 1.00271889 410
