Quoting from the markdown bar breaks formatting

[AmandineLP]

I copy pasted a bunch of text including paragraphs and line breaks, selected it all, clicked on the 'quote' button and all my formatting was lost, putting everything as a single line text

It seems that the default behaviour when quoting in draft-js is to quote every "block". So bullets will become individual blockquotes instead of there being one big blockquote encapsulating all. Inline formatting appears to survive however.

i guess this is related:
i observed that quoting messages with numbering just works until the numbering because the numbers (including its text) is ignored. ☹️

no idea if it is the same for bullets. - i will report if i fall across such case (and still remember).

From my side, the composer does not break the formatting, it is the formatted message that is badly formatted.

Original message:

a

b

I select all and I click on the "Quote" button:

> a
> 
> b

I send the message.

The message is displayed as:

> ab

And if I edit the message, the content is:

> 
ab

The source of the message sent:

{
  "type": "m.room.message",
  "content": {
    "msgtype": "m.text",
    "body": "> a\n>\n> b",
    "format": "org.matrix.custom.html",
    "formatted_body": "<blockquote>\nab\n</blockquote>\n"
  }
}

body is correct while formatted_body is incorrect.

This is still broken because of #8786

@MazeChaZer would you consider this fixed now then?

I'm going to close this for now as it appears to be fixed. Please file a new issue with details if you feel that there are further improvements to be made 👍
