Text background opacity does not impact banner names on maps

When the Text Background setting in accessibility is set to "Everywhere," the names of banners on maps remain unaffected by changes in the "Text Background Opacity" setting. Relates to MC-241524 and MC-146028.

Steps to reproduce

1. Navigate to your accessibility settings menu
2. Set the "Text Background Opacity" slider to "0%" and the "Text Background" button to "Everywhere"

3. /give @s minecraft:white_banner[minecraft:custom_name="Lovely"]

4. Place the banner
5. Use a map on it

Observed outcome: The name's background remains unaffected by changes in "Text Background Opacity".
Expected outcome: The name's background should be influenced by adjustments in "Text Background Opacity".
