Layout properties specified through templates not applied on io.write_image()

[rom-burner]

Eg specifying a height and width as properties in a template for a figure and using the show() method renders the figure correctly, but write() method using kaleido defaults to plotly.io.kaleido.scope.default_height and default_width of 500x700, regardless of what is specified in the figure's template. Not tried with orca.

Easy fix is to re-specify figure dimensions again in io.write_image() call, but should this be necessary?

Thanks for the report @rom-burner. I talked about checking the template's layout width in #12, but looks like I didn't end up implementing that in #18.

I think we can handle this here

Kaleido/repos/kaleido/py/kaleido/scopes/plotly.py

Lines 81 to 82 in 76ff4d3

	width = width or layout.get("width", None) or self.default_width
	height = height or layout.get("height", None) or self.default_height

As a workaround, do you get the template width/height if you set the scope's default_width and default_height to None globally?

import plotly.io as pio
pio.kaleido.scope.default_width = None
pio.kaleido.scope.default_height = None

See also plotly/plotly.py#2651 ... would be nice to just fix this everywhere and have the static renderers always honor layout.{width|height} falling back to layout.template.layout.{width|height}

Agreed
