[Teak and Ulmo]: Completion checkmark(green tick) disappears on refresh for randomized Problem Bank XBlock

[kmccormick (Kyle McCormick)]

Thanks for the report @meet1.

Could this be related to fix: apply library_content transformer to all ItemBankMixin xblocks by MaferMazu · Pull Request #37830 · openedx/openedx-platform · GitHub ? @braden if so, would you have time to re-review and backport that?
