In the 'TryGetSensorGateFrustum' method in the CameraEditorUtils.cs (https://github.com/Unity-Technologies/UnityCsReference/blob/master/Editor/Mono/Inspector/CameraEditorUtils.cs) the near plane size calculation is different form far plane size and includes a typo.

Far: planeSize.y = camera.farClipPlane * Mathf.Tan(Mathf.Deg2Rad * camera.fieldOfView * 0.5f);
Near: planeSize.y = 2.0f * camera.nearClipPlane * Mathf.Tan(Mathf.Deg2Rad * camera.fieldOfView * 0.5f);

The near planeSize.y multiplication by 2 seems incorrect as it is not required and has not been spotted before as the near plane calculation is never called in any editor code and the near vector array is always passed in as null so the conditional check always skips that part of the code.

Reproducible with: 2019.4.39f1, 2020.3.35f1, 2021.3.4f1, 2022.1.3f1, 2022.2.0a16
