When clicking on Hanging Pream Leaves with bonemeal, it moves from not grown state to grown state as it should, however doing the same on fully grown state will make player pick-up the berry AND use bonemeal on now ungrown Hanging Pream Leaves.

An expected result was bonemeal not trigger on the same click when Hanging Pream Leaves are matured.
A good example of the expected behaviour could be observed from Berries - using bonemeal on Berries doesn't cause those berries to both drop and then grow more - it will make them drop from picked bush if it's fully grown or make it grow more berries if it could grow further.

If I could also throw in a suggestion while at Hanging Pream Leaves:
It would be amazing if you could use Bonemeal on the Pream Leaves for them to then grow Hanging Pream Leaves under them - similarly to how you can obtain Mangrove Propagules by using Bonemeal on Mangrove Leaves.
