LIGHTROOM: Paint with Clone Tool Out-of-Canvas areas created by Perspective Correction

In Lightroom 5 I really like the Perspective Correction tool which always produces white Out-of-Canvas areas as a result of image deformation.
As a "constain crop" very often would cut out a lot of interesting details, I love to Crop the image a bit wider.
The problem are the white areas remaining that were not present in the original, undistorted image.
I would love to fill them in with the Clone Tool, but it does not seem to work on those areas!

To make a complicated story simple just look at this image:

My aim here is to fill in the bottom left white space by simply cloning the missing part of the column.
This is a super-easy job which I could do with Lightroom clone tool in seconds.
Why is it not working?
This forces me to first export the image to a dummy, than re-import it in Lightroom and do the simple editing.
I would love the ability of painting over those white areas directly in Lightroom as part of my workflow, without the need of this time-consuming workaround.

Thank you very much for your feedback.

I think the reason the clone tool is not working on the white area is because there are no image pixels in that area to replace. In other words you're trying to clone beyond the edge of the image and LR never lets you do that. The only thing different in this case is that the edge of the image has been transformed into a shape that is not rectangular anymore.

Yeah, I guess that is the problem too.
By the way, the final image will be the one with square corners, including the "old" (now rounded) corners.
Wouldn't it be easy to allow the Clone Tool over those areas too?
It is anyway treated as a simple overlay by the program (its action can be instantly turned on/off) so I don't see the point in constraining the overlay over "original image pixels" only.
