False positive for `needless_return` (there is no return!)

Summary

The following file is generating what I believe to be a false positive needless_return lint when there is no return statement at all:

https://github.com/DioxusLabs/taffy/blob/b66bd6bfaa3368aa105ad01e697ea2ff3da6b11a/scripts/gentest/src/main.rs

Lint Name

needless_return

Reproducer

I tried this code:

Ran cargo +nightly clippy --workspace
In the root dir of https://github.com/DioxusLabs/taffy/
At commit b66bd6bfaa3368aa105ad01e697ea2ff3da6b11a

(Sorry, I don't have to time to reduce this right now)

I saw this happen:

warning: unneeded `return` statement
   --> scripts/gentest/src/main.rs:158:78

There is also a second unrelated warning (but I believe this is legitimate).

I expected to see this happen:

No warning as there is no return statement.
