Polymer 1.x: Modal paper-dialog appears behind its backdrop
问题 Does anybody have any advice for fixing the problem of a modal appearing behind its backdrop? So far, I have tried making sure I have all the necessary imports (including <paper-dialog-scrollable> ). I also tried a "hack-fix" (suggested by someone) involving setting z-index: auto in the css of paper-header-panel . Neither works. It's worth noting that the <paper-dialog> tag works just fine. Until I add the modal attribute. Any ideas? Similar issues Appearing around the internet are this issue
