Function syntax highlighting with attribute proc macro

[gtsiam]

So, I turned on experimental proc attr macro expansion for a custom macro, but syntax highlighting seems to really not like it when I pass expressions from the attributes to the output. Here's the macro (well, the shortest version of it where I could get the error):

struct FilterAttr {
    filters: Vec<Expr>,
}

// Parse attributes as Punctuated<_, Token![,]>
// impl Parse for FilterAttr { ... }

#[proc_macro_attribute]
pub fn filter_minimal(attr: TokenStream, item: TokenStream) -> TokenStream {
    let func = parse_macro_input!(item as ItemFn);
    let attr = parse_macro_input!(attr as FilterAttr);

    let filters = attr.filters;
    let vis = func.vis;
    let name = func.sig.ident;
    let tokens = quote! {
        #vis fn #name() {
            let dummy = 0i32 #( .wrapping_add(#filters) )*;
        }
    };

    tokens.into()
}

#[filter_minimal(1, 2, 3)]
pub async fn test() {}

Here's the problematic highlighting:

From some testing, it seems that the issue only appears when I try to put the attributes in the output. In every other case, highlighting seemed to work correctly. I also tried changing FilterAttr::filters to Vec<Lit>, but the issue persists.

Dupe of #9185 I believe?

Possibly? It's hard to tell, since I'm not familiar with rust-analyzer's internals.

On a second look ye this seems to be a dupe of that one, closing in favor of it.
