Blockquotes formatting is faulty in threads

[matthias4217]

Description:

In blockquotes, the language name is shown as text in threads.

Steps to reproduce:

I have sent the following message in a conversation, then in a thread. A \ has been added in this issue before the triple backquotes, which is not present in the chat messages.

\```python
def my_function():
    trucà = 42
    return ""
\```

Expected behavior:

This is what I have in a conversation with myself. Everything looks fine.

Actual behavior:

This is what I get when posting the same block in a thread. The language name is displayed, and the syntax coloring doesn't work on the first line.

def my_function():
    trucà = 42
    return "�"

pasted the above without the back-slash('')[
