After examining specialized variants in Shandalar shops, UI disappears #12304

Describe the bug
On Android, I was in a Shandalar adventure shop, and after I finished examining a specialized variant, the UI was gone. Only the background remained.

To Reproduce

1. Visit an adventure shop, click a card with the "specialize" keyword to examine it.
2. Click the "specialized" button at the bottom for the carousel of variants (no side swiping needed for this bug).
3. Click outside the current variant image to dismiss the carousel.
4. At this point: nothing is visible: no cards, no buttons, just the shop background.
5. Clicking the Android OS back button restores the shop to its default view.

I was looking at Sarevok the Usurper.
I bought the card, and the deckbuilder did not have this bug when I examined it there.

Expected behavior
In the deckbuilder, when I click outside the carousel to dismiss it, I'm returned to the inventory/deck list. (Not the original unspecialized large card image)

Operating System
2.0.16-snapshot-10.06 on Android 15.
