Issue with water and strings

^{Update by} @unknown^:

The bug

When you drain water, some water 'stickies' to strings, this is only a visual glitch.

How to reproduce

1. Place some strings on the ground.

2. Place water, so water floats into the strings.

3. Remove the water source.
   → ❌ Some water will 'sticky' to the strings til you update the block.
