Mangrove leaves broken with Silk Touch do not stack with those broken without Silk Touch

I got 3 different stacks of leaves that won’t stack with each other at all 

Even weirder than them not stacking, if you place them from one stack and re-silk touch them they don't go back in the same stack. I just took down half the leaves from a single tree, ended up with a stack of 14 and a stack of 62. The 14 and 62 would not stack together. So I placed 2 leaves from the stack of 62 and re-silk touched them for 2 entirely new stacks of 1. Now if I place and break from the original stack of 62 they split between those 2 new stacks and don't go back to the original stack they came from. Or the stack of 14. 

ETA 1.19.2 seems to have fixed this in chests (I can get all the leaves to stack together if I put them in a chest then try to stack them in said chest) but still getting multiple stacks in inventory.
