The requested change is to simply change the default value of Gate fit from Horizontal to Vertical

The problem:
When you set your camera and want to simply enable Physical camera to see all the parameters or start tweaking it. There is severe visual pop. Its distracting and often ruins the composition.

We discussed with Pavlos that this change can be made and makes sense. But should not be backported to not break existing projects, also mentioned in migration guide.

Reproduction:
1) Add camera to any project
2) Enable the Physically based settings

Expected: No visual change (with default physically based values)
Actual: The camera is zoomed
