The Bug:
The "Can hold a mixed stack of items" text within bundle tooltips doesn't have a shadow.
This is inconsistent because text within all tooltips always has a shadow.
Steps to Reproduce:
Obtain a bundle and hold your mouse cursor over it.
Look closely at the text within the bundle's tooltip.
Observed Behavior:
The said text doesn't have a shadow.
Expected Behavior:
The said text would have a shadow.
I can confirm this issue.
