When I set the gamerule functioncommandlimit to value high enough to support importing a complex structure, I get a error message saying the maximum value is 10,000

Steps to reproduce:

enter command /gamerule functioncommandlimit 250000

Expected result:

   The expected result is the gamerule updating that limit to the new value.

Actual result:

   The gamerule is not updated and the following message is displayed, 

      The number you have entered (250000) is too big, it must be at most 10000

This seems related to an earlier bug reported here . https://bugs.mojang.com/browse/MCPE-38845
