ssh autocomplete for fish shell no longer works

Dupe Check

• I have searched Warp bugs and there are no duplicates

Describe the bug

Recently SSH autocompletion with my fish shell worked fine, something broke it in the past week or so. This is mainly a rubber ducking thread and I'll post my results here. This might be a fish issue, might be a warp issue. But I do know that if I open a non-Warp shell then SSH autocompletion works as expected.

To reproduce

type ssh then <TAB>. A list of IP addresses appear, but no hostnames. It appears that it does list suggestions IF the hostname is in ~/.ssh/config but NOT any Include <path>/* directives.

Expected behavior

List of hosts in ~/.ssh/config to return.

Does this block you from using Warp daily?

No

Is this a Warp specific issue? (i.e. does it happen in Terminal, iTerm, Kitty, etc.)

Yes, this I confirmed this only happens in Warp, not other terminals.

None

Start by reproducing ssh plus Tab in Warp using fish 3.7.1 on macOS 14.5, then compare its suggestions with a non-Warp terminal and inspect how SSH host entries from ~/.ssh/config and Include directives are discovered. Done means included hostnames appear in Warp's autocomplete as they do elsewhere.
