Widows Bite: If I have Widow’s Bite in play and I reveal a minion with quickstrike, which resolves first?

Quickstrike triggers when a minion engages a player and minions enter play engaged with the player who revealed them, thus Quickstrike and the “Response” on Widow’s Bite have the same timing trigger. Keywords have timing priority over “Response” abilities, so Quickstrike resolves first.
