When reloading datapacks, the recipe tabs get removed for players with an open inventory. The recipe tabs come back when reopening the inventory.
How to reproduce
Type "/reload" into the chat

It's not because it takes time to reload. The reload-time has no effect on the tabs. The problem is that the tabs are removed after the datapack has been reloaded. Then they won't come back before reopening the inventory. This might be very small and not a priority at all, but it's a bug nonetheless.
What exactly do you think reloading datapacks does? It refreshes the recipes for furnaces, crafting tables, and the like, among other things. Therefore, I think this should be marked as Intended Behavior, because the reloading takes a few seconds to accomplish.
