Summon menu bugs target while casting.

[mtwango]

Scenario:

• cast a spell, tested with field spell energy field
• while the spell is being casted, cast a summon creature spell and select creature from menu
• the first spell hits you instead of your target.

If you only open the summon menu, but don't select a creature, the spell lands fine, so it seems selecting value in dialog changes the target to you.
