Description:

Clicking off the accept/decline window when casting teleport or summon holds the request in perpetuity. The caster cannot cast another teleport or summon spell, because they already have a request pending now.

Steps to reproduce:

1. Cast teleport on a target

2. Click off the prompt with target

3. Observe

Note:

This seems to effect every accept/decline prompt in the game. The target also can do whatever after clicking away.
