Tested this for  4.8.0.21 beta and current stable release. Chromecast with Google TV (4K) version 2022. emby works fine for all of my older chromecast versions (including third generation), but for the current generation with Google TV resume and jump does not behave as expected: it loads some time and then jumps back to beginning or does not stop loading. Tried the same video with old chromecasts and everything works fine.
