Th cut trick worked up until about a month ago. Nothing changed at the server end so it must have been a Chrome change
There really isn't anything I can do. I am able to delete it every time, but sometimes it takes a lot of random typing and deleting before it goes and when it goes it's always a surprise. There's a pattern to doing it which I can't determine.
I suspect it'll suddenly get fixed, but I'll raise it with the devs again.
