The Bug
When an item with a non-white rarity is highlighted over in the inventory or (thanks to MC-130145) selected in the hotbar, its name will display as colored. However, if the item is renamed and then inserted into an item frame, the text displayed will still be white, regardless of the rarity of the item.
The ominous banner's name displays normally, however.
Steps to Reproduce
Obtain an item frame and place it down.
Give yourself an item with a rarity color that has been renamed.
/give @s minecraft:enchanted_golden_apple{display:{Name:'{"text":"MC-132199"}'}}Look at the color of the item's name within the item frame, and take note as to whether or not it's displayed in its rarity color.
Observed Behavior
Renamed items with rarity colors don't display their colors when inside of item frames.
Expected Behavior
Renamed items with rarity colors would display their colors when inside of item frames.

Note that the name also is not italic, while in the inventory, a renamed item is always in italic (unless you set italic to false in a command)
Confusingly. this also affects 18w45a, despite the implemented illager banners correctly displaying name colour.
