Quick actions executed in multiline inline code, when placed on it's own line

Quick actions should not be executed when they are in inline code or multiline code blocks. However, they seem to be if they are in a multiline inline code block.

For example, this does not create a label (which is correct) (note that the space in front of /label was added to ensure that the code block did not remove the actual label command, which is also a problem)

```
 /label ~"Test Label"
```

This also works correctly (does not add a label)

`/label ~"Test Label"`

However the following adds the label, and shouldn't (note that the space in front of /label was added to ensure that the code block did not remove the actual label command, which is also a problem)

`
 /label ~"Test Label"
`

This was noticed in issue #24083 (comment 284623163)
