Webclipper stucks

I tried to grab this page https://github.com/learn-vuejs/vue-patterns/blob/master/README.md but the webclipper just display : “loading…” and no popup at all.

FYI: It works in my env: Joplin 1.0.104 on macOS and WebClipper 1.0.6 on FF 61.0.

Update: the popup shows up, but the created note is rendered as a blank document.

It seems this is due to:

<style>
* {
 margin: 0;
 height: 100%;
 width: 100%;
}
</style>

Add this to any note and it is no longer being displayed (only in raw/editor)

Question: Is this a bug or is it a feature (of markdown)?
