Disable the playing field when power is tapped

When you tap on the flashing icon and the players power selection pops up, please please please disable the playing field behind it.

Twice now I've brought up Spidey to activate his blue power and apparently missed tapping it correctly, made a match behind the scene, and then watched as Hulk downed him with a Thunderclap, all while his powers menu was still in the foreground.
