Inline copy code icon has weird display behavior

[Cordelya]

Summary: copy-code icon has before and after line breaks in inline codeblocks, and doesn't show at all in fenced codeblocks.

Environment:

• Logseq 0.6.6
• Copy Code plugin 1.1.2
• OS: Windows 10
• Other plugins: logseq-calendars-plugin, logseq-quicktodo-plugin, logseq-recurrence-plugin, logseq-smartblocks (all up to date)
• All plugins were installed via the Marketplace (ie not manually)
• Logseq is generally not otherwise modified.

Consider the following block:

Automatically remount the share at boot. Add the following to `/etc/fstab`
```ini
//remote/share /local/mountpoint cifs credentials=/home/username/.smbcredentials,uid=username 0 0
```

As a screenshot:

When rendered, it displays like this:

It looks as though the "copy code" button is being inserted into inline codeblocks with line breaks before and after. The button does not appear at all when I hover my mouse cursor over any fenced codeblock.

I have not altered the button's positioning from the default.

Let me know if you'd like me to try anything or if you need more information.
