Comment:
Looks like I found [solution](https://github.com/fish-shell/fish-shell/blob/master/share/functions/fish_title.fish)

Maybe add patch for it?
Never do that ...

change
"[$(prompt_hostname | string sub -l 10)]"
to
"["(prompt_hostname | string sub -l 10 | string collect)"]"

no error for me after change...
