Question: multi-line command substitution in script vs interactive

[PatrickF1]

In one of my own fish scripts, I have a line that looks like

set variable (
        command1 |
        command2 |
        command3
)

So I was really surprised that when I tried to type it out in the interactive shell that this was printed

 ~  set variable (                                                                                                   
fish: Unexpected end of string, expecting ')'
set variable (

Is it expected that in the interactive shell you can't do multi-line command substitution?

No, it's not expected, the editor is overzealous here.

Woohoo found another bug! Thanks for all your work on the fish shell faho!
