I've started noticing that bees are getting stuck, or are just refusing to move after interacting with Pink Petals from the Cherry Grove biome.

Whatever you see in my screenshot, is all there is to it. They are literally getting stuck on flowers, right around their nests. The nests are unobstructed, and moving the bees manually (moving them by nudging them off the block), fixes the issue. It's a pathfinding issue but the bug you linked doesn't seem to be quite the same issue.
Based off the information provided right now this seems to just duplicate MC-170410 (bees get stuck on blocks pathfinding to flowers, or in this case flower leaves) or the report mentioned previously. If you are unable to add clear steps to reproduce the issue, it's impossible to tell if it's differrent.

Create new world.
Go to Cherry Grove, or any flower biome where bees generate.
Observe bees getting stuck after pollinating.
Seems pretty obvious to replicate and a waste of time for me to sit here and say this.
As an aside, this might not be something everyone can replicate.
It's a pathfinding issue, as I've said. What the issue is exactly varies from cause to cause. In my screenshot, the bees have pollen and stay on any petals seen. They seem to be getting stuck on blocks, that otherwise shouldn't be causing obstructions because they can't pathfind to the nest/hive. Flowers, pink petals, Leaves, fences. It's a total pathfinding issue.

Thank you for your report!

When I search for an issue I report, nothing comes up that is similar to my bug. The bug I'm reporting is that they're getting stuck on the way to the hives, not on the way to flowers. Subtle difference, but a difference all the same. Would be nice if people could read.
Would MC-261691 describe your issue? The bees could be trying to pathfind towards a block they can't reach, and thus get stuck. Consistent and clear steps to reproduce the behavior would be very helpful to have, if you can come up with a consistent setup. 🙂
