Copy button in screen copies also callouts

[tomschr]

Problem Description

Reported by in openSUSE/obs-docu (see Reference below).

In a screen with callouts elements )<co/>), the callout numbers are copied too.

For example, this is how it looks like in HTML:

<pre class="screen">
<span class="callout" id="co-obsbg-uc-basicprj-description">3</span>
...
<button class="clip-button">Copy</button>
</pre>

Expected Behaviour

When hitting the "Copy" button, the JavaScript should essentially ignore all <span> elements with a class="callout" attribute within <pre>.

@GGayathri3: If you have time, could you have a look? I see the "clip-button" text in different JavaScript files:

$ ack clip-button suse2022-ns/
[...]
suse2022-ns/static/js/script-new.js
281:      class: "clip-button",

suse2022-ns/static/js/script-purejs.js
270:    clipButton.className = "clip-button";

suse2022-ns/static/js/script.js
271:          class: 'clip-button',
