Only the First Line of Multiline Comments Is Highlighted

Issue

Multi-line comments are only "highlighted", usually dimmed, on the first line.
Single-line comments are fine.

Though not properly highlighted, the comments actually work.

Thanks for the report. It might take me some time to get this fixed, but I don't think it will be too difficult.

I haven't done the work to confirm this, but Typst is probably giving us multiline spans for multiline comments, which we convert directly to multiline semantic tokens, which are prohibited in many LSP clients.

Assuming that is correct, these tokens just need to be broken up. Fixing it is nontrivial but shouldn't take too long.

I think the same problem is with codeblocks:

```rust
let x: usize = 1;
```

does not highlight the last line
