Expand selection does not correctly expand to method arguments

[WaffleLapkin]

Summary

When using expand_selection on a method name, it first expands to the receiver and only then covers the arguments, instead of selecting the whole method call at once.

Reproduction Steps

I tried this:

1. hx
2. :set-language rust
3. write

   fn main() {
       a.b(c);
   }

4. Go to b
5. Use expand_selection (alt+o)

I expected this to happen: selection covers the whole a.b(c) method call.

Instead, this happened: selection only covers a.b.
