Summary:
In the java version, the "randomTickSpeed" gamerule does not affect the speed at which tadpoles hatch from frogspawn. In bedrock, on the contrary, "randomTickSpeed" affects the hatching speed. MC-249308 - Java report this issue in java edition which was resolved as a feature request.

Steps to reproduce:

1. Place down some frogspawn.
2. Set the "randomTickSpeed" gamerule to a high value in an attempt to increase the speed of the frogspawn hatching.

   /gamerule randomTickSpeed 3000

1. Wait a couple of seconds watching the frogspawn.

Observed results:
The speed at which tadpoles hatch from frogspawn would be affected by the "randomTickSpeed" gamerule.

Expected results:
The speed at which tadpoles hatch from frogspawn is not affected by the "randomTickSpeed" gamerule.
