Pufferfish triggers tripwire without colliding with it upon reloading the game

Pufferfish placed on waterlogged halfslab triggers tripwire above when enemy aproaches it by enlarging its size.

This still works correctly in 1.14. until game is reloaded.

Reloading the game causes tripwire to detect smallest state of pufferfish, which is below water level. Pufferfish can not be therefore used as mob/player detector reliably.

When player (or other mob) aproaches bugged Pufferfish, it changes its size to medium and corrects tripwire output to none. Biggest state of Pufferfish still gives output as expected. (true)

To reproduce just build setup shown in attachment and reload the game. Pufferfish is placed above waterlogged halfslab with tripwire above it. Attachment shows false output given by tripwire upon reloading the game.
