Disclaimers

• I have searched the issue tracker to check if the issue has already been reported.
• My issue happened while using mods.

What happened?

The Mirror X and Mirror Y buttons are not affected by the Reset to prefab button. For clarity's sake, these buttons should be reset to their initial values (usually off) when defaulting every other value.

Reproduction steps

1. Spawn item in Submarine Editor
2. Mirror it on either the X or Y axis (or, both)
3. Press Reset to prefab
4. Spawned item stays mirrored
