if I use background-image: url() within css, this leads to page reload in the
background within a style block, the page get loaded a second time in the
background. A url tag with no content should be ommited.

This is a major bug for Website developers who allow users to change the HTML
code they send to browsers.

Reproducible: Always
Steps to Reproduce:
1. browse to a file with an emtpy url() statement in the css part
Actual Results:  
Page get loaded twice

Expected Results:  
Load the page once

No, an empty url() value is a relative URI which resolves to the base URI, in
this case the URI of the stylesheet. If you don't want to reload your stylesheet
as a background image, you probably meant background-image: none.
