Hovering over argument with same name as outer variable produces nothing

[mousetraps]

Testing microsoft/vscode#12600

Using the following code and a breakpoint at the location specified location

var screenName = 'hello';

setTimeout(function() {
    console.log('done');
    a(screenName);

    process.exit();
},1000)

function a(screenName) {
    console.log(screenName); // SET BREAKPOINT HERE
}

hovering over screenName at this position should produce the string "hello", instead, no hover appears. Changing the name of the argument resolves the issue.
