bug: Neovim 0.12.1 crash - redraw_ruler: Assertion 'attr == HL_ATTR(HLF_MSG)' failed when rendering UI/messages

[theSprog]

Did you check docs and existing issues?

• I have read all the noice.nvim docs
• I have updated the plugin to the latest version before submitting this issue
• I have searched the existing issues of noice.nvim
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

0.12.1

Operating system/version

Linux (WSL2), x86_64

Describe the bug

After upgrading to Neovim 0.12.1, Neovim hard crashes (aborts instantly) when trying to open certain UI elements like the :Lazy window or when specific messages are triggered. The crash logs indicate a C-level assertion failure in statusline.c related to message highlight attributes, which seems to conflict with how noice.nvim handles ext_messages.

Steps To Reproduce

1. Use Neovim 0.12.1.
2. Setup noice.nvim with default message handling (or routing msg_show events).
3. Open Neovim and run :Lazy (or trigger an event that heavily updates the message area/ruler).
4. Neovim instantly crashes and drops to the terminal.
5. the following crash log is captured：nvim: /usr/src/debug/neovim/neovim/src/nvim/statusline.c:543: redraw_ruler: Assertion `attr == HL_ATTR(HLF_MSG)' failed.
6. Disabling the message routing in Noice prevents the crash and allows Neovim to run normally:

require("noice").setup({
    messages = {
        enabled = false, -- Disabling this avoids the assertion failure
    },
})

Expected Behavior

The UI/message should render smoothly without causing a fatal C-level assertion failure in Neovim's redraw loop.

Repro

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    { "folke/noice.nvim", opts = {} },
    -- add any other plugins here
  },
})

Same issue here, seems I can't use nvim on Linux anymore, but the same config works in MacOS.

Same issue here, seems I can't use nvim on Linux anymore, but the same config works in MacOS.

Just updated Neovim to 0.12.2 and it seems the bug is gone!

This suggests the issue might have been on Neovim's side rather than noice.nvim.

I'm happy for the maintainers to close this issue
