Wrong leading comments in body when parsing function

[Alphapage]

Hello,
You can find an example: https://astexplorer.net/#/gist/0b644cf2308d56067cb8ac917c91f151/0b11735e5c90f30abe210c1271050e8a809e4ae4

Input Code

var o = {
    
    test(arg//an arg
    ,arg2//arg2
    ,arg3//arg3
      // arg33
    )//comment
  //comment2
  {
        console.log(arg)
    }
} 

Babylon/Babel Configuration

Babylon v6 and v7

Expected Behavior

I think body BlockStatement should not insert function parameters comments to leading comments or objectMethod, function and class method should add trailing comments.

Current Behavior

last parameter comments of function or method are added to body leading comments.
no trailing comments in function tree

Your Environment

software	version
Babylon	6 or 7
node	6.10
npm	*
Operating System	*

Thank you in advance for your answers.
