Pagebuilder 1.0.0_rc2 not recognizing "background-attachement" values. I can change it to "fixed" but it defaults back to "scroll". If I do an "inspect" on the element there is no "background-attachement" css attribute, if I add it manually through the browser console it works as expected. Therefore, the Pagebuilder is not picking up the change in value from the PB GUI and storing it and/or not adding it to the element's style.
