Pull request #245 to fix issue #17116 mentioned in jupyter-notebook repo gives too much output

[kiliansinger]

I reported microsoft/vscode-jupyter#17116 for the vscode-jupyter plugin stating that the element variable is not exposed in javascript magic environment. It was fixed in this pull request.
#245

And indeed output now appears but additionally some source code is output.

Following example:

%%js //the next line is only necessary in jupyter notebooks
element.setAttribute('style', 'white-space: pre;');console.log=function(text){element.textContent+=text+"\n"}

let age=42 //type annotations are not available in javascript you need to use typescript
           //that is translated into javascript by a compiler
console.log("I am "+age+" old\n")

output:

 (function(){
                    let gotToUserScript = false;
                    try {
                        // Required by JS code in Jupyter notebook renderers such as ipyvega.
                        // We're not fully supporting ipyvega yet, but this ensures the scripts will not fall over and will work with minimal effort on our part.
                        const context = {
                            outputs: [{
                                metadata: {}, data: {}
                            }],
                        };
                        // Required by JS code in Jupyter notebook renderers again, even scenepic (Microsoft Python widget) uses this.
                        const ele = document.getElementById("78a4cefb-af83-488c-8ab5-2152c172af23");
                        (function (element){
                            gotToUserScript = true;
                            element.setAttribute('style', 'white-space: pre;');console.log=function(text){element.textContent+=text+"\n"}

let age=42 //type annotations are not available in javascript you need to use typescript
           //that is translated into javascript by a compiler
console.log("I am "+age+" old\n")

                        }).call(context, ele);
                    } catch (ex) {
                        console.error('VS Code Renderer failed to render output', ex);
                        if (gotToUserScript) {
                            throw ex;
                        } else {
                            // Something went wrong in our script that was generated by us.
                            element.setAttribute('style', 'white-space: pre;');console.log=function(text){element.textContent+=text+"\n"}

let age=42 //type annotations are not available in javascript you need to use typescript
           //that is translated into javascript by a compiler
console.log("I am "+age+" old\n")

                        }
                    }
                })();I am 42 old

Expected output:

I am 42 old

I'm unable to repro this issue.
Please can you share your VS Code, Jupyter extension and Notebook Renderer versions installed?
