Parent editor-style.css doesn't load if you use a child theme

[superpoincare]

I have a self created child-theme of twenty twelve but if I want to use the classic editor block in the block editor.

However, the editor seems to only load the child editor-style.css

Hence, for example the font used is Noto Serif.

If I activate the parent theme twenty twelve, however, it uses Open Sans (correctly).

So the bug is that in child themes, parent theme editor-style.css needs to be loaded.

(All seems well with loading of both parent and editor-style.css in the classic editor plugin)
