I'm bringing this topic back up, because I am watching the github issue and have found no recent progress.

I don't think people understand just how important this feature is for mobile retention. It is 70% faster for switching tabs on a page than complete page reload.

The few bugs and continued integration shouldn't be too hard, the biggest being comments fail (which looks like it may have been fixed, I will have to look)

@Anton L would be great to see more additions and fixes for this is next beta 😁
