I cannot replicate this sorry. Are you playing on a server or is your client modified?

Were there any grass blocks near the trial spawner?
Can confirm
Please elaborate further where to find this gap
This sounds more like a feature suggestion
Can also confirm. I guess the solution here is to just forget the forward slash, since it works without it. It might even be intentional

Can confirm. You don't have to shift click though.
[media]This is an intended feature. Hitting your head with a splash potion will give you the full duration, while splashing away from you will give you less duration (including your feet).
Found out that the same thing happens when switching from "peaceful" to any of the other difficulties.
This is intentional, since the game looks for what liquid you are targeting at and not what block. Since there is no outline for targeted liquids, this can be confusing, but it does make sense.
