How to specify percentage width as default?

In the Google Maps settings, you can specify the default map width in pixels, but I'd like to specify it as a percentage instead (i.e. full width of parent container).

I have a feeling that this will not work via a CSS change since the width is added as an inline style via JavaScript.

Could you please tell me how to achieve this? (and possibly add this as a feature request? :slight_smile:
