Issue Summary

If you copy text from another source (web, plain text editor, code editor) and then paste it into the Code Block or the No Format macro, the leading white spaces are removed. This effectively removes all code indentation.

Steps to Reproduce

1. Type some indented code in a plain text editor or code editor
2. Copy the text to your clip board (right-click copy or CTRL+C/CMD+C)
3. Create a page
4. Insert the Code Block macro
5. Paste the previously copied code

Expected Results

The copied text is pasted exactly as is.

Actual Results

All the leading spaces are removed, subsequently removing all code indentation.

Workaround

None. We need to manually indent the code.
