Asynchronous Effects + Confirmation Box leads to match lock

Tilwin90

Haven't experienced a soft lock due to confirmation boxes in a while... that is until today. 
This is in tandem with asynchronous effects (that don't lock the game until they finish resolving but occur in parallel with the remaining actions of the turn).

Here is today's scenario:
1) Have Lyra & Razia onto the battlefield
2) Hold a full mana Aurelia and a full mana Swords to Plowshares in hand (in this order)
3) Opponent has no creatures onto the board
4) You have nothing else on the board
5) Perform a match

Up until now, all is well. But here is what happens next:
1) Aurelia gets put onto the battlefield
2) It grants abilities to Razia synchronously
3) Granting abilities to Lyra happens in parallel with the Confirmation Box for Swords to Plowshares
4) Click 'Not Now'

Expected: Swords to Plowshares is not cast and we go next to combat phase
Actual: Confirmation Box persists and no actions are possible (choosing and confirming a target or trying again 'Not Now')
