How to change the position of the gradient when reversing the y axis?

[danifox-s]

I have reversed Y axis by doing this:
yaxis: { reversed: true, }
And I'm getting this:

Is it possible to change the position of the gradient so that it is at the bottom?

Does not seems like is currently possible.
This closed issue #1337 discussed a possible "reverseFill" option, but I dont see anything on documentation.
