Crosshair in camera is based on pan location when entering camera view

When you enter a camera view, the crosshair can be off-center or even appear to be missing. This is because it's location is retained from the previous view (1st person or 3rd person). When pressing Use to exit the camera view, the new view is reset to forward/centered, so entering camera view again immediately will result in the crosshair reappearing/recentering.

Repro to place crosshair off-center:

1) Set up a camera to View on the toolbar

2) In 1st or 3rd person, adjust (pan) the camera so that it is slightly off-center

3) Use View on the toolbar to enter the camera view - note that the crosshair is off-center

4) Press Use to leave camera view, then choose View camera again without changing current view. Note that camera crosshair is now centered again

Repro to place crosshair disappear (out of frame):

1) Set up a camera to View on the toolbar

2) In 1st or 3rd person, adjust (pan) the camera so that it is 90 degrees left or right

3) Use View on the toolbar to enter the camera view - note that the crosshair is not visible

4) Press Use to leave camera view, then choose View camera again without changing current view. Note that camera crosshair is now visible again
