Lingering Water Bottle is not working properly

Let's start with what is a Lingering Potion? A Lingering Potion is a potion that leaves a cloud effect after being thrown, which lasts for a certain amount of time. Lingering Potion cloud duration = 30 seconds if we use the wiki material. And recently I became very interested in this point.

And I found an interesting bug that you might think is a feature request, but I don't think so. After all, Lingering Water Bottle is also considered a Lingering Potion, but for some reason when you throw Lingering Water Bottle, its cloud lasts for a few seconds, compared to other Lingering Potions. If the duration of her cloud lasts less than 30 seconds, then how is Lingering Water Bottle different from Splash Water Bottle?

Steps to reproduce the bug:
1) Take any Lingering Potion and Lingering Water Bottle.
2) Now, throw them one by one, and you will notice how the Lingering Water Bottle cloud disappears in a few seconds, while the Lingering Potion cloud disappears after 30 seconds.

I think this bug needs fixing.
