use_color_mode panicking with "already mutably borrowed: BorrowError" in reactive_graph

[nlfiedler]

Simply calling use_color_mode() is enough to cause the error, which appears in the terminal window.

Start by creating a new actix-based leptos project: cargo leptos new --git https://github.com/leptos-rs/start-actix

Update Cargo.toml to upgrade the leptos crates from 0.7.0 to 0.7.8 (the latest as of today), then add leptos-use = "0.15.7" and these two lines in the [features] section:

  "leptos-use/ssr",
  "leptos-use/actix",

Then add use leptos_use::{use_color_mode, UseColorModeReturn}; at the top of src/app.rs and let UseColorModeReturn { mode, set_mode, .. } = use_color_mode(); after the on_click line in the HomePage component. Then start the app with cargo leptos watch and attempt to open the page. You should see this in the terminal:

The issue is still present with Leptos 0.8.1.

I am encountering this issue with leptos 0.8.2, leptos-use 0.16.0-beta2, and axum
