Symmetry mirror the tool preview

When i activate the horizontal or vertical symmetry, I want the tool preview (with every tool, as implemented in latest updates) to show on the mirrored side.

At this point, it only shows the preview of the current effect on the side im hovering over the mouse. If i have a 1 pixel brush, it shows that pixel with the selected color, but not its morrored effect.

This might seem small, but when were doing art, our brain gets “used” to it and we often mirror it to see it with fresh eyes. Having the symmetry mirror the preview would be really helpful, and makes sense for it.
