When someone pastes formatted text into a code block opened with three tildes (`…~~~`), the Markdown composer adds formatting markers such as `**` to the pasted text. The same paste into a code block opened with three backticks stays unchanged. This commit makes both kinds of code block preserve pasted text. Pasting formatted text outside a code block still converts it to Markdown as before. ### Reviewer notes #### Before this fix The composer incorrectly converts the HTML representation to Markdown, producing `prefix **bold**` inside the tilde-fenced code block. ![Before the fix, the Markdown composer contains prefix followed by bold formatting markers inside a tilde-fenced code block](https://github.com/user-attachments/assets/be9fe779-d2f6-4e67-af66-5de0f155f6e1) #### After this fix The composer uses the plain-text representation inside the code block, producing `prefix bold` without formatting markers. ![After the fix, the Markdown composer contains prefix followed by plain bold text inside a tilde-fenced code block](https://github.com/user-attachments/assets/fcfea879-ab19-4f94-805c-32778d77cc00)
