Copy Code (WYSIWYG Editor) Found the topic that show my problem. But no [solve]

I have some LaTeX code in my Editor looks fine but the Copy Button only copy first line of the “PRE” marked code. LaTeX Code I try different tries but still only first line – where I can find that COPY button in my Theme ProDoc?

I can select the Code Press the Button still only first line in cache 🙁

And in Theme / Additional I toggled ON Line Numbers and Copy to Clipboard 😉

The one Line example from ProDoc work in one way Copy button … but its only ONE Line xD

Work Not:

<code class="language-css">    .navbar__submenu {<br><code class="language-css">        background: #ffffff;<br><code class="language-css">        box-shadow: 0 0 6px rgba(52, 58, 65, 0.15);<br><code class="language-css">        left: auto;<br><code class="language-css">        margin: 10px 0 0;<br><code class="language-css">        opacity: 0;<br><code class="language-css">        position: absolute;<br><code class="language-css">        top: 100%;<br><code class="language-css">    }

Work xD:

<code class="language-css"><span class="token selector">.navbar__submenu</span> <span class="token punctuation">{</span>
        <span class="token property">background</span><span class="token punctuation">:</span> #ffffff<span class="token punctuation">;</span>
        <span class="token property">box-shadow</span><span class="token punctuation">:</span> 0 0 6px <span class="token function">rgba</span><span class="token punctuation">(</span>52<span class="token punctuation">,</span> 58<span class="token punctuation">,</span> 65<span class="token punctuation">,</span> 0.15<span class="token punctuation">)</span><span class="token punctuation">;</span>

        <span class="token property">top</span><span class="token punctuation">:</span> 100%<span class="token punctuation">;</span>
