Springs can merge to create permanent water.
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.
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.
