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?

I don't think it's using a TOML grammar library, just conf-mode bundled
with EMACS "The major mode is Conf[TOML] mode defined in conf-mode.el".
I think an extra newline was inserted in the TOML I pasted (in the
comment before the URL), it should be 4 lines total. I've attached the
exact file.

From what I can tell Alastair is using conf-mode, not toml-ts-mode.
Alastait: toml-ts-mode is a new builtin tree-sitter based major-mode for working with TOML files.
If you have issues with conf-mode and certain TOML files, you could try that instead. I just tried it with your test-files and I don't see any incorrect fontification, so it seems to work fairly well.
Eli: If there's a bug to fix in conf-mode, I'm going to assume it would be better to CC the conf-mode maintainer than the toml-ts-mode maintainer. It might gain more traction.

Thanks. Does the patch below give good results (I don't have too many
conf files around to test it).
Stefan, does the fix look good to you?

AFAICT this rule is not even activated in for TOML files.
The patch below seems to DTRT for me.
[ I'd even argue that it should (goto-char end). ]
[ I found the culprit after noticing that the number of
`font-lock-type-face` elements in the list in the `face` property was
the same as the number of characters between the two "sections". ]

Oh, it already does, sorry. OK I pushed it to `master`.
I think this is it.
Can the OP confirm it fixes the problem for them?
