Decorators on nested classes attach to wrong class

[loganfsmyth]

Input Code

@id
export default class Sample {
  method() {
    class Child {}
  }
}

Babylon/Babel Configuration

{
  "plugins": ["decorators"],
}

Expected Behavior

Should output an AST with the decorators property attached to the outer Sample class.

Current Behavior

Outputs an AST with the decorators property attached to the Child class instead.

I'm assuming we're not clearing and then restoring the tracked decorators state when entering a nested class declaration.

Isn't it the same as #259?

Ah definitely is, not sure how I missed that.
