No Fix Planned Can't undo City of Brass

Was playing a league yesterday and tapped for the wrong color of mana with my City of Brass. Now I was already aware that you can't undo it once you yield through the trigger to deal yourself 1 damage, but the damage trigger was still on the stack and I had priority. I had not clicked "No" or interacted with the City of Brass damage trigger in any way. I can't think of for what reason I was unable to undo it - I did have "stack triggers automatically" enabled, but that shouldn't pass through the trigger afaik.

If you are making a payment and tap the City, you can undo this. But if you just tap this while holding priority, this works as intended and can't be undone. (This is why R&D eventually made Mana Confluence)
