Describe the bug

1. Start typing.

2. Copy some text (from anywhere) to your clipboard

3. Use the Ctrl-K shortcut to start a new inline code block or just click the button

4. (Optional) start typing in your inline code block (the bug happens either way)

5. Paste your text (Ctrl-V)

Expected: The text will be pasted into the inline code block, and the cursor will be at the end of the text

Currently: The text is pasted as plain text. If there had been text in the inline block, the block closes and the text appears after it. If there hadn’t been text in the inline block, the block vanishes, never to be seen again (if you toggle to markdown mode, there is no evidence of the block.

The same also happens if you select any text within the inline code block and then paste - if you have three words in the block, and select the middle one, then paste, it will split the inline code block into two (first and third words) and then add your pasted text as plain text between the two inline code blocks.
