Cancelling Render clears the image when Save Buffers and Noise Reduc is on

Description

System Information
OSX Latest

Blender Version
Broken: Daily Build (26-10-2017)
Worked: (optional)

When enabling Noise Reduction and Save Buffers (Performance Tab) the image clears all progress when cancelling (ESC) the Render. Disabling Save Buffers or Noise Reduc shows correct behaviour (show the progress it reached)
(Rendering on CPU btw)

Thanks for looking into it.

Although denoisier is new and a little bit experimental, I did not found a warning, a line in manual or release logs about the issue proving that it is a known limitation.

So, I confirm that enabling Save Buffers option does not allow to see rendered tiles of a canceled render with both GPU and CPU rendering while denoiser is used.
