Could not make it work

Using version 1.0 of the Elementor Inline SVG plugin with Elementor Pro 1.9.1, WordPress 4.8.2, and the Astra theme. The plugin widget appears in the Elementor tool area, and if an SVG file is loaded using it, the graphic is rendered in the widget’s little preview box. But the graphic does not show in the main Elementor editing area — there’s just a blank rectangle. Adjustments to the graphic (size, position) cannot be observed in real time. Instead, the page has to be viewed outside of the editor to see the effects.

I do not know if this is the way it is supposed to work or not. Maybe the widget is misbehaving in my environment (MAMP), or is not compatible with some other plugin.
