Capture Source not changing in Planar Reflections

Changing the Capture Source in Planar Reflections is not working as expected. Without being able to change the source, Post Process Materials are not rendering in the Reflection.

Reported in version 4.25.3(CL 13942748). Tested in versions 4.25.3, 4.24.3(CL 11590370), and 4.23.1(CL 9631420) with same results.

1. Open a new project
2. Enable and make a Planar Reflection
3. In details, change the Scene Capture>Capture Source setting to any other than Scene Color(HDR) in RGB, Inv Opacity in A, like Normal in RGB or Final Color(LDR)

Result: Nothing changes, the Planar Reflection ignores the change of the source in the setting.

Expected: The Planar Reflection should change the source.
