Roundcube is very unreliable in Safari on MacOS

[BrianP]

I've been using Roundcube for a couple of years now, using Safari under MacOS on an M1 MacBook Pro and found it to be very unreliable. It constantly lost contact with the server or failed to send replies, to the point where I would copy my replies to the clipboard before clicking Send. It's frequently the case that, because Chrome is the most widely used browser, many developers only test on Chrome - as a Mac user, I frequently find this problem, even with high profile web sites, like the Waitrose online ordering site here in the UK. Fed up with constantly having to reload it, I finally tried Roundcube on Chrome a few days ago, and what a transformation - perfect performance! This is fine for me as a tech-aware person, but I have many Mac-owning friends who haven't a clue what Safari is or that there is an alternative. Can I please ask the developers to investigate Roundcube in this environment and see if these issues can be resolved. I'm happy to provide any diagnostics on request, but 5 minutes of trials on an equivalent Mac setup will show the problems
