> When editting TOML files with conf-mode[toml] the face property is being 
> set badly on certain characters.  This occurs in Emacs 29.3 (running 
> with -q) but has been present in older versions.  Steps to reproduce:
> 
> 1. Create a file test.toml containing the following:
> 
> 
> [package]
> name = "test"
> # See more keys and their definitions at 
> https://doc.rust-lang.org/cargo/reference/manifest.html
> [dependencies]
> 
> 2. Navigate to the d in dependencies and evaluate
> 
> (text-properties-at (point))
> 
> The output for me looks like
> 
> (face (font-lock-type-face font-lock-type-face font-lock-type-face 
> font-lock-type-face font-lock-type-face font-lock-ty\
> pe-face font-lock-type-face font-lock-type-face font-lock-type-face 
> font-lock-type-face
> 
> 
> It looks like something is wrong in the font-lock setup and the same 
> face is being applied very many times.

I cannot reproduce this here, neither in Emacs 29 nor in Emacs 30.
What version of the TOML grammar library are you using?

Jostein and Yuan, can you please look into this?
