There are several moz-prefixed values for cursor property we may need to support.

It seems cursor is a bit different that the keyword definition is in style_traits rather than style, and I'm not completely sure what's the best way here.

I have tried to make these lines be gecko-specific. But `[cfg(feature=gecko)]` seems not work with macro.

You can add `$(#[$attr:meta])*` in the macro to support this.

Please try making the new values Gecko-only.

Hi Xidorn, I tried to add `#[$attr: meta])*` to the macro (see the latest patch), but I always got the following compilation error:

```

 0:06.90 error: local ambiguity: multiple parsing options: built-in NTs expr ('css') or 1 other option.

 0:06.90    |     ^

 0:06.94 error: Could not compile `style_traits`.
```

Do you know what the correct syntax is to make it work?

This looks good to me. Probably worth double-check with Manish or emilio whether they think this is fine.

Do you need `cfg(feature = "gecko")` in `gecko.mako.rs`?

emilio, are you fine with the approach in the patch?
Flags: needinfo?(xidorn+moz) → needinfo?(emilio+bugs)
Looks fine to me. I've seen this pattern used elsewhere too, but I forget where...

No, we don't need it. I think gecko.mako.rs is already gecko only.
