Menu not displaying in chrome with polymer 2.0 - polymer-2.x

I am new to polymer framework. I am using polymer 2.0.0-rc.3 and latest version of chrome. But below code is not displaying menus.Only "Hello World" is printed in browser. The developer tools console does not show any error.
Below is the code
test-app.html
<link rel="import" href="../bower_components/polymer/polymer-element.html">
<link rel="import" href="../bower_components/paper-menu/paper-menu.html">

Does any body have any idea about error? Any guide as how can I debug it to find error?

paper-menu has been deprecated in Polymer 2. As this comment says:
This element is deprecated in favor of paper-listbox, which has been ported already to Polymer 2.0.

How can I avoid bundling Vuetify and use from CDN?

I'm trying to decrease the bundle size of my Vue project, which scaffolded by the vue-cli, by using CDN of firebase, Vue, and Vuetify.
So, I've added links of these CDN in public/index.html as follow:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">

<link type="text/css" rel="stylesheet" href="https://www.gstatic.com/firebasejs/ui/4.8.0/firebase-ui-auth.css" />
<link href="https://cdn.jsdelivr.net/npm/vuetify#2.x/dist/vuetify.min.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/vue#2.x/dist/vue.js"></script>

Add config.externals to vue.config.js as follow:
module.exports = {
"transpileDependencies": [
"vuetify"
],
chainWebpack: (config) => {
config.externals({
firebase: 'firebase',
'firebase/auth': 'firebase',
firebaseui: 'firebaseui',
vue: 'Vue',
vuetify: 'Vuetify',
'vuetify/lib': 'Vuetify',
})
}
}
Then, the report.html created by issueing yarn build --report indicated that the Vuetify is still in the bundle even other firebase and Vue is going away as follow:
Is there any wrong or insufficient steps?
If you are using vuetify from vue-cli-plugin-vuetify (vue add vuetify), treeshaking and auto component import is enabled by default, by using vuetify-loader.
If you look into the source code of vue-cli-plugin-vuetify, it only uses vuetify-loader if it is present in your package.json. So removing vuetify-loader from package.json should disable this behavior.

context is not defined

I am trying to draw a picture into a div to be able to make the drag effect later. It seems that the function that has to draw the image is not working right. Maybe someone has a hint why?

Any help is appreciated!
Load mocha.js first. Your own comment is correct.

Angular Routing not working - blank screen

I am stymied by this issue. For some reason the Angular routing is not working at all. I simply get a blank screen. All of the modules are loading, there is no error in the console, and if I enter Angular in the console, it works. Yet, I get a blank screen.

Polymer 0.4 JSONP

I'm playing around with Polymer 0.4. I'm trying to do a jsonp request using polymer-jsonp component which I've installed using bower.
But it's not working, it looks to me like the polymer-jsonp component is not compatible with Polymer 0.4 and it has been deprecated according to this https://github.com/PolymerLabs/polymer-jsonp/releases/tag/0.3.0
I can see in my network panel that the polymer-jsonp comoponent is being correctly imported but even though it has the "auto" parameter it does not make the request at all. I'm not running it throug any JS code, I'm expecting it to run automatically because of the auto param and to bind it results to the results param value.
May I wait for a compatible version to be released or is there any way to use it or some alternative?
EDIT:
Here is an example:

Thank you very much.
The jsonp element really should be updated for core, it's just a nuisance that is hasn't been yet. However, I looked at the code, and I believe the old one should work just fine. It's possible you just have a simple problem in your setup.
I can see in the browser console that it is not being imported.
Make sure you have a <link> tag in your application that imports the element. Probably something like:
<link rel="import" href="bower_components/polymer-jsonp/polymer-jsonp.html>
