rightclicking a fence with a block item while having an entity on a lead desyncs the block

If we interact with (rightclick) a fence while holding any block item and simultaneously holding an entity on a lead, the client will try to place the block. The server assumes that the only action of the player was to put the lead onto the fence/into a LeashFenceKnotEntity and doesn’t acknowledge the placed block, causing it to be removed without adding the block back into the players inventory.

I am not absolutely certain what the expected behaviour is even supposed to be here, but I think either the block placement or the LeashFenceKnotEntity needs to have definite priority on both server and client.

How to reproduce:
Simply summon any mob and place down a fence. Put any block and a lead in your hotbar, then put the mob on the lead. Switch to the slot containing the block and try placing it on the fence. Notice that the block disappears from your hotbar.
