View/ Lights - Move to Camera makes ParaView unstable

Let me start by saying that to a light, "Move to Camera" means move the light to the current camera location. This bug assumes that "Move to Camera" is NOT really "Move Camera".

• Linux, 5.7.0-RC2, builtin server.
• Sources/ Cone. Apply.
• Not needed, but rotate counter clockwise 90 degrees.
• View/ Light Inspector.
• Add Light.
• Move To Camera.

ParaView is now really weird.

• The mouse has picked up a hand icon, rather than the default pointer.
• You are no longer moving the object with the left mouse button! This can be stopped by using the right mouse button, then the left.

This needs to be fixed.
