Preloading/caching issue in Safari

See original GitHub issue

It looks like Safari reloads images again on each trial even though it has already preloaded stimuli at the beginning of the experiment. I’ve only tested it with the image-button-response plugin though. See discussion #1547.

Hi @becky-gilbert, thanks for working on this. I don’t use Safari myself and have been asking participants to not use Safari, so I’m not entirely sure if there’s still a problem. But I ran your 6.3 example in Safari (see gif below) and it seems like there’s still network activity going on on each trial (I don’t see such activity in Chrome/Firefox).

This looks like it might be a clue to solving the issue: https://stackoverflow.com/questions/61566984/async-image-preloading-by-promise-all-not-working-on-non-chrome-browsers

@becky-gilbert we could try adding this decide to preloading functions. I’ll work on it when I have some dev time available, but feel free to try it if you beat me to it.
