Description

Any regular widgets (WordPress widgets, not elementor specific widgets) save, yet do not show updated values in the input/select fields. So whenever I drag a widget, fill it out and update it, the widget saves my settings and it displays correctly, but upon a reload or later access the front end editor shows the default widget values. Just to be extra clear on this, it DOES save, but the 'saved values' are not being displayed in the fields, instead the default values for the widget are shown.

I checked if this was also happening when adding widgets via the: Appearance > Widgets menu, but this was functioning as how it should.

I went inside some of my own widgets and saw that in the function: public function form($instance) the $instance variable returned an empty array (in the front-end editor of Elementor), so that would explain why it can't show the saved settings. I can't recall if Elementor (Free) always acted like this.

Is this a bug or a limitation of the free version?

Steps to reproduce

1. Drag a Wordpress widget in the editor.
2. Fill out some of the settings.
3. Save it.
4. Reload/Refresh the page and the widget shows the default values again.
