rust highlights: only the last identifier in attribute macros gets highlighted

[lovelymono]

Summary

When using attribute macros, such as #[warn(...)], only the last identifier gets highlighted with @function.macro.

#![warn(clippy::std_instead_of_alloc, clippy::std_instead_of_core, clippy::alloc_instead_of_core)]

In this case, ideally only std_instead_of_alloc, std_instead_of_core and alloc_instead_of_core would get highlighted, without highlighting clippy, but highlighting all identifiers would also be fine.

Alternatively, not highlighting anything would also look good.

This is a consequence of #9436 - there's a bug in the highlighter. #12972 will fix this
