Copy contents of a field to clipboard

#1

The macro here lets me copy simple snippets to clipboard.

But one of my fields carries this:

{{!!lede}}<br><br>

Some text <br><br>

<nowiki />#tag1 #tag2
<$list filter="[enlist{!!category}]">
  #{{!!title}}

And I wanted a button to copy the whole contents. So, I did this:

<<copy-input "{{!!lede}}<br><br>

Some text <br><br>

<nowiki />#tag1 #tag2
<$list filter="[enlist{!!category}]">
  #{{!!title}}
</$list>">>

I face two difficulties. One, the html formatting is lost (<br><br>). Secondly, when it encounters the first ", it copies only upto there.

How do I solve this problem?
