After using teleporting to another dimension (eg. with mods like https://www.curseforge.com/minecraft/mc-mods/fabrichomes and https://www.curseforge.com/minecraft/mc-mods/fabricwarps) the thirst bar indicates "full" even tho it is not. In the video I made for CodedSakura/FabricWarps#2 it can be seen at timestamps 00:00 (overworld) compared to 00:06 (end) and at the end (overworld) when drinking it reapers correctly 01:03:

Example fix for status effects and exp bar from the tp mod as reference: CodedSakura/FabricWarps#2 (comment) https://github.com/CodedSakura/FabricCrossDimTPFix/blob/master/src/main/java/eu/codedsakura/fabriccrossdimtpfix/mixin/TPMixin.java

Will the fix be backported to Minecraft 1.16? (It's okay if not.)

No plans to work on older versions

Should be fixed with def9879
Thanks for reporting
