You can fish with a fishing rod through the blocks. You can also pull up items
Steps to reproduce:
1. Throw the rod on the water, or on the item and move away
2. In some way to make so that the way was closed by blocks
Observed results:
The fishing line of the rod passes through the blocks, and at the same time can work
(For clarity in the video, I used glass, but the bug can be reproduced with any solid opaque block)
Expected results:
The fishing line cannot work through the blocks

Ideas on how to fix it
Perhaps if the fishing line had the physique of a leash on the Bedrock edition of Minecraft, the bug could have been avoided. Well, it's probably high time to update the rod, because it looks pretty weird
