Legend overflow

[Zaf4]

Hi,

Similar to #846 the legend overflow exists, this time more vertically.

The legend is fine with when ggsize(800,600) but when I add ggsize(600,400), this happens...

to highlight the overflow with the rectangles
+ theme(plot_background=element_rect(color="red", size=4), legend_background=element_rect(color="blue", size=4))

panel shrinking and allowing multi-column legend column automatically, if legend(s) will overflow, could be a good fix.

Do I understand correctly that you know how to make multi-column legend manually (see example in guide_legend()) but wish the legend to "wrap" automatically?
Also note that in recent v 4.5.1. you can make legend more compact by reducing its key height/key spacing: https://nbviewer.org/github/JetBrains/lets-plot-docs/blob/master/source/examples/cookbook/legend_theme.ipynb

Exactly!

This is a very good feature as well, thanks for adding this. But I think legend overflowing kind of breaks the plot.
