When changing the text background opacity in the chat settings, the scoreboard sidebar stays unaffected, rendering some text colors barely readable. It would be a lot more accessible if the text background setting would also change the scoreboard background (or better, a seperate slider for scoreboards)

Reproduce

• Construct a scoreboard which displays some information.

  /scoreboard objectives add MC-227576 dummy
  /scoreboard objectives setdisplay sidebar MC-227576
  /scoreboard players set @s MC-227576 12345
  

• Set the "Text Background Opacity" chat setting to 100%.
• Type something into the chat and press enter.
• Compare the background opacity of the chat to the information displayed in the scoreboard.
  → Notice how the "Text Background Opacity" setting does not affect the background opacity of the scoreboard overlay.

Expected Result

The setting would affect the opacity of the scoreboard background
