 Hi @andyimatest,

 Welcome to Trac! First, my apologies that it took so long to receive a
 response.

 The first thing that sticks out to me in your example is that the HTML
 class names are invalid. The `;` and `:` characters cannot be used in the
 class attribute.

 I have tried to reproduce the issue you are describing, but I am not
 having any success. Using the Classic Editor, When I paste your example
 text in to the Text editor, switch to the Visual editor, and then switch
 back to Text, I see the following:

 {{{
 <pre class="brush: csharp; title: ; notranslate" title="">test test test
 </pre>
 }}}

 The outer `<pre>` tag us eliminated.

 When using the block editor, if I switch to Edit as HTML, paste the
 example, and switch back to Edit Visually, the result is the following:

 {{{
 <pre class="wp-block-preformatted"><pre class="brush: csharp; title: ;
 notranslate" title="">test test test
 </pre></pre>
 }}}

 The outer `<pre>` tag is preserved with the matching closing tag, but a
 class is added.

 Are you still able to reproduce the issue you described originally? I am
 going to mark this as a close candidate, but please do provide more
 details if you can.
