BHV-10367: AlwaysViewingPanels: Unexpected Path is Created for background source

**Issue**

An extra space was being added after url colons in the style attribute, resulting in wrong paths

**Fix**

modifying a regular expression in Control.normalizeCssStyleString() to not add spaces after colons preceded by http or https

Hi @kranga-lge, this seems to work for the given issue. Can we make this more generic so we don't need to handle all the variants of URLs (i.e. http://www.enyojs.com:80/image.png). Perhaps we could modify this to be broader and examine both property name and value, something like `.replace(/(;?)\s*(\w+):\s*/g, '$1 $2: ')` (courtesy of @Djspaceg). This has the side effect of adding an extra space before the first property, but you should be able to just trim this, or you might be able to use this as a basis for something broader.
