Save inline style into a proper css rule: Popup not visible

@Lava this happens when there is no CSS stylesheet included on the page (or stylesheets are ignore / not loaded in PG). Looks like some kind of issue in this case because the css/style.css should be included on the page. Can you double check if it is?

Also, update to Pinegrow plugin 1.0.1.

Thanks for your help!
