While a fishing rod is cast, the player model in the Survival Inventory has a long string attached to the character.
To Reproduce
Cast a fishing rod. Open your inventory to the Survival Inventory tab. Your character has a string attached to them now!
(A quick note: in my screenshot, I'm using a resource pack to make the menus look like they do in Java Edition. I'm still using the Bedrock Edition.)

The texture pack is called PC GUI, if you're wondering.
