Hey guys-)

I have templates that were created in one of older Elementor versions(around 2.3.0).

It uses stretch section option on many sections.

Now with 2.5.0 - 2.5.5 it works fine on the front end(stretches), but in edit mode, it doesn't stretch section at all.
In 2.4.7 it works fine in the front end and the edit mode.

In frontend.js line 1660 I have added console log:

if ('stretch_section' === propertyName) {
			console.log(this.getElementSettings('stretch_section'));

And it returns undefined on each change of the stretch section option, instead of empty value or section-stretched.

I attach template on which it happens.

If you need any more details - let me know.

Hope for the fix.

With kind regards.
