Pasting markdown into Notion doesn't work as documented

[safinea]

When I paste markdown text into Notion, I see some issues:

• pasting strikethrough does in fact work with double tilde markup
• when pasting with a trailing backslash, the linebreak is not created, it just shows a '\'
• if a line ends with formatting (e.g. bold) and the next line starts with formatting, then the linebreak between them is ignored. This should probably be considered a bug for Notion, though, not for the docs.
• pasting emojis does not work (e.g. pasting 🔥 just keeps the text). It doesn't work when typing it out either...

As stated, they're not necessarily 'issues in the documentation, but maybe should be Notion bugs.
