Yellow tab corner on 'prefer unidolized image'

i selected that i prefer the unidolized image for a card that i idolized but in my deck it appears without the yellow tab corner thingy that all other idolized cards have. is it possible to have the unidolized image with the yellow tab to show that it is idolized?

No files or tests are named. Start by tracing how card images and idolized status are rendered in a deck, then compare the selected unidolized-image path with other idolized cards. Done means the preferred unidolized image still displays the yellow idolized corner indicator.
