Death, firing, and shop screen bug

[Owen CMYK]

How to reproduce:

1. Die while firing weapon
2. Open shop while still holding mouse button
3. Release moues button
4. Wait for respawn

Your character will start firing after they spawn, and will continue until the shop menu is closed. The shop menu normally doesn't have this behavior, instead allowing you to stop firing by releasing the mouse button. Note that I tested this as Wraith in Hero Sandbox and by dying to the Guardian, but I imagine it works in other contexts.
