Springs can merge to create permanent water.

Summary

Springs will merge and produce permanent water sources if close to each other.

Steps to reproduce

https://pastebin.com/pMFmCQnd Right click on the mob where multiple water sources can spawn at the same height, and then they will merge.

Current behavior

Water springs can merge to form permanent sources that aren't removed when the spring effect ends.

Intended correct behavior

If they could not merge, it would be great.

Proposed fixes

Make the water sources not merge, or remove them if they do merge.
