kevin schaaf has helped me fix issue. please see thread.

note first need latest version of polymer (currently 5.2) bower. go core-animated-pages.html , find piece of code -

if (!olditem) {     this.applyselection(this.selecteditem, true);     return; }

now add this.async(this.notifyresize); after applyselection -

if (!olditem) {     this.applyselection(this.selecteditem, true);     this.async(this.notifyresize);     return; }

that's it! code should working without calling updatesize or other tricks.

i think after 5.2 fix included package don't need this. it's simple change need make.
