colorbar ticks and bounding box not affected by `foreground_color` option

[marcusps]

Details

When plotting a heat map in particular, I cannot seem to change the color of the ticks on the color bar (the ticks themselves are a problem, but the tick labels are affected correctly), or the color of the bounding box around the color bar. This is problematic when plotting on a dark background and attempting to get a white foreground.

With this simple example

heatmap(0.01*randn(8,8), clim=(-1e-1,1e-1), c=:bam25)
plot!(
    size=(800,500),
    foreground_color=:red
)

I get the results

with GR

with PythonPlot

Also note that adding foreground_color_subplot=:red does not change anything.

And I verified that using theme(:dark) or theme(:lime) from PlotThemes behaves in a similar manner (same issue).

A work around was proposed in the Julia Discourse server, but the current behaviour still seems to be a bug.
