When beacon power level is changed, the GUI doesn't update until closed and reopened

The bug

An open beacon GUI does not update whenever beacon power level or active state changes.

How to reproduce

1. Place this structure file in .minecraft\saves\<world_name>\generated\minecraft\structures.
2. Go in that world and run:

   /setblock ~ ~ ~ structure_block{mode:"LOAD",name:"mc-1429",showboundingbox:1}
   

3. Get an iron ingot, stand on the pressure plate and put the iron in the beacon.
   → After the beacon is deactived, you can still select an effect
