SVG size in editor

this is due to the fact that some svg code do only have viewBox dimensions and no internal width and height information.
those svgs are handled as if they have width and height : 0x0

So on avia-builder.css there is a rule :

/* @since 5.6.9    make sure that svg is visible in backend - needs to add logic for frontend !!!  */
#avia_builder img[src*=".svg"],
.wp-admin .avia-modal img[src*=".svg"] {
	width: 1500px;
}

that makes all svg visible on backend. For example – very important for image with hotspots. Image ALB Elements etc.

so maybe it would be better to exclude those svg inside avia_textblock and replace that rule above by:
( because on text_block the images do get width and height information by tiny-mce editor.)

#avia_builder div:not(.avia_textblock) > img[src*=".svg"], 
.wp-admin .avia-modal div:not(.avia_textblock) > img[src*=".svg"] {
	width: 1500px;
}

but that had to be done in that original file and should be best implemented to enfold in next version.
