The bug

When hovering over a non-empty shulker box item you get a preview of the items contained and the stacks sizes. This number shares the styling of the items name. I expected this number to always be styled the same. 

This is problematic, because you can not preview the size of item stacks with obfuscated names.

How to reproduce

1. Run in a command block:

   /setblock ~ ~ ~ shulker_box{Items:[{Slot:0b,id:"minecraft:stone",tag:{display:{Name:"{\"text\":\"Bold\",\"bold\":\"true\",\"color\":\"red\"}"}},Count:1b},{Slot:1b,id:"minecraft:stone",tag:{display:{Name:"{\"text\":\"obfuscated\",\"obfuscated\":\"true\"}"}},Count:1b}]}
   

2. Pick up the shulker box
3. Open inventory and hover over the shulker box item
