Splash potions duration gets shortened too much when splashing on your feet

The recent changes in the preview made the splash potion matching the normal potion duration:

Splash potions now have the same duration as drinkable potions

As looking at the inventory, the duration time description has changed to match the normal potions. However, after testing and checking it out, the duration was shortened a lot more, compared to Java, almost closer to old duration time, despite the recent parity change.

1:30 minutes -> 1:19 minutes
3:00 minutes -> 2:38 minutes
