Describe the bug / provide steps to reproduce it

I doubt this is a Zed bug and probably more of a syntax tree bug (I think zed uses treesitter?) but regardless I figured I would post it here since I have no idea where to go to address it. C-String literals are a relatively new addition to rust

The actual symptoms of the bug seem to be inconsistent, ranging from simply strings not highlighting separately to breaking syntax highlighting for many tokens until a new quote appears.

Taking the following code and pasting it into a new rust file/module should provide the same result as the screenshots attached below (it appears this also happens in GitHub Markdown Preview)

use std::ffi::CStr;

pub fn invalid_highlighted_sample_code() -> &'static CStr {
    c"b" // When the string literal contains exactly one character, it continues string literal
         // highlighting until the next open quote
}

pub fn normal_highlighted_sample_code() -> &'static str {
    "this is a normal string"
}

pub fn non_highlighted_sample_code() -> &'static CStr {
    c"this is a broken string"
}
