Copy icon appears incorrectly for code blocks within blockquotes

[alexey-skoblin]

Issue Description:

Expected Behavior:

• The copy icon should not appear for code blocks that are nested within blockquotes.

Actual Behavior:

• The copy icon is erroneously added to each line of the code block, even though it's part of a blockquote.
• When a code block is at the end of a blockquote, the copy icon may render outside the blockquote's visual boundary, leading to a misaligned and "broken" appearance.

Steps to Reproduce:

1. Create a new note in Obsidian.

2. Add a blockquote that contains an inline code block or a fenced code block.

3. Example 1 The copy icon appears on each line when editing.

```markdown
> [!note]+ Сообщение от Алексей
> **Дата:** {date} {time}
> **Сообщение:**
> ```text
> 18:39
> ```
>
```

4. Example 2 The copy icon is displayed after the blockquote on the next line.

```markdown
> [!note]+ Сообщение от Алексей
> **Дата:** {date} {time}
> **Сообщение:**
> ```text
> 18:39
> ```
>
```

5. Observe the behavior in edit mode.
