The brush continues brushing the targeted block if pause is pressed while holding down the button, and continuing after the button is released while on a LAN world

Forgot what I said earlier.
This bug still intended but not for the reason I said earlier, it's because to consistent with other items.
For example: You still throw trident when your game paused in multiplayer. Eating food, drinking drinkable item, using shield and spyglass; and loading bow and crossbow also have the same behavior.
Brush also count as an item, meaning that if the bug is fixed, it will create an inconsistency between the items that I listed above.
That's intended, you cannot pause an online game
