Bugs are fine, but this wasn't really a bug. It was lack of foresight.
I haven't used Konsole, but I do like this "recent" focus on terminals and have used many of the newer ones. Dailydrived st,alacritty,wezterm,ghostty,kitty,foot (probably forgot some) and I live for the regex pattern matching copy shortcuts etc.
I learned about OSC8 because my terminal (whichever it was) used one of its features and I didn't know it was possible to do that. My immediate thought was, how is the security?
And it is very disappointing to see how little effort people have spent on that. That is really one part that I expect more from modern incarnations of the old terminals where I can sort of forgive them for the lack of security posture.
I like ghostty, I really do. But this is not a good look, and to be clear it isn't just ghostty. Without looking for it I've stumbled upon several OSC8 and OSC52 bugs (in other software) recently.
