Fish prompt does not show when I create a new terminal tab

Dupe Check

• I have searched Warp bugs and there are no duplicates

Describe the bug

Basically, whenever I create a new tab in Warp, the fish prompt does not appear. No part of it--the file path part, the > part, or the right prompt part--none of it is present. I see a brief flash of the text "Starting fish...", then it goes away.
Now--I can type in commands, and everything works, and as soon as I type in basically any command (valid or invalid), the prompts all appear correctly, and stick around.
The problem does not occur if I source my config.fish file, or run exec fish. It only happens when opening a new tab.

To reproduce

1. Start Warp.
2. Open a new tab.

Expected behavior

I expect to see the standard fish prompt that I've defined in fish_prompt.fish and fish_right_prompt.fish (or whatever those files are named).

Additional context

This is my config.fish, but it should be noted that this problem was occurring when my config.fish was empty, so I don't think that's it.

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 the missing prompt when opening a new Warp tab on macOS Sonoma with fish 3.7.1, then compare it with sourcing config.fish or running exec fish. Trace Warp's fish startup handling, including the brief "Starting fish..." phase; done means the configured left and right prompts appear immediately in a new tab without requiring a command.
