ScreenCapture.CaptureScreenshotAsTexture is capturing the editor when NOT using Free Aspect

I have a script attached to my character. The script calls ScreenCapture.CaptureScreenshotAsTexture() from within an IEnumerator.

I collect a bunch of Texture2D objects and then at some point, I export each of them to file as a JPG.

I do this with:

 var shots = new List<Texture2D>();
 //populate shots
 
 using (var memStream = new MemoryStream())
 {
     foreach(var shot in shots){
         File.WriteAllBytes(filePath, shot.EncodeToJPG());
     }
 }

For some reason, when I check out the saved files, it is clear that part of the Editor is being captured...

This only occurs when the game view is set to use something other than Free Aspect Any idea why? Bug?
