Image export ignores figure layout (using Kaleido) #2933

Hi!

Thank you very much for your awesome library 🥇

I am having some issues about figure sizing with svg render. I think a reproducible example is very visual:

With default render (plotly_mimetype+notebook) the layout correctly changes the figure size:

But if I try it with svg render it ignores the layout 😢:

Do you know how to avoid this problem? I need an uniform strategy, that with the same code returns same figure size, excepting the rendered type.

Thank you in advance 👍
