Capture Source not updating in Planar Reflection actor

Hello. When I change the Capture Source inside the Scene Capture 2D, it updates correctly. But when I change the Capture Source inside Planar Reflection, the capture source does not change and is stuck on the default “SceneColor (HDR) in RGB, Inv Opacity in A”.

Here is a video demonstrating the issue:

I found this forum post were they have a similar issue:
https://forums.unrealengine.com/development-discussion/rendering/1802917-planar-reflections-and-post-process-materials

One person in the thread posted that this has been confirmed as a bug and posted as UE-99613

However, when I check the issue report it has been marked as “By Design”. Is this really the case? Why even have the option to change the Capture Source if not changing it is “By Design”. This seems to be a mistake in Epic’s part were a valid issue has been inappropriately marked. Can someone at Epic please have a look at this again?

It seems to still be an issue in 4.26 according to this forum post:

Thanks for your time!
