Slowing down html5 On mobile when gif files are used

hi

When I use gif animate file(120 frame 176*529 px) in Html5 canvas , everything is fine on the pc' browser, but on the mobile's browser(chrome), the speed slows down like slow motion.

I test export pic as texture with resolation: 1 and max saze: 800 ،I did not see any effect. and i used trace bitmap for all gif's frame in stage, Again I saw no effect in mobile.

this is my file: https://drive.google.com/file/d/1OFQCJsaa2AVHHeGTS0p_Di-IZKlfSK-N/view?usp=sharing

Thanks
