i am displaying an animated gif in an iframe. i use srcdoc to set the iframe content. the gif is loaded as css background image. if i reload the exact same srcdoc again, the animated gif freezes. maybe this is due to caching?

observations:
- it works when i add a random hash to the filename
- it works when i load the image via <img>
- it works in chromium
