Add text-bg-blend-{mode} to blend text and background (image)

[stoachup]

text-bg-{color} are very nice. I'm trying to blend text with background image in a card. Img is of class card-img-top wheres text is in q div card-img-overlay. I can't figure out how to properly style the div using mix-blend-mode property to exclusion. My guess is that it comes from how cards are structured.

A text-bg-blend-{mode} (exclusion in my case) class would definitely be helpful when overlaying text on a picture.
