Hey guys, I just wanted to follow up on these two bugs, here.
As far as I can tell, the completion bug is completely fixed, and I can find no trace of it in the system.
As for the date issue, I have been unable to repro it with Big Sur/Safari 14.1, nor on latest iPhone. If you can still reproduce it in your environment, please supply:
1. make/model of device
2. browser version
3. a link to a page that shows the bug
In the meantime, I've closed the issue in our tracker, but I will open it again if somebody chimes in with the above info. Sorry for the long delay, and thanks for all the help.
