PyPlot heatmap in Atom: colorbar overlaps plot

[yha]

After some recent update, PyPlot heatmaps inside Atom started having the colobar overlap the plot:

using Plots; pyplot()
heatmap(1:10,1:10,(1:10)*(1:10)')

Also, the plots are not correctly sized, leaving unused space in the plot pane, and the default fonts also seem much too small now. I believe the incorrect size issue was there for quite a while, but the change in font size is new.

The heatmap looks fine when plotted outside Atom.

Package versions:

 - Plots                         0.17.3
 - PyPlot                        2.6.0
 - Atom                          0.6.16
