Code paragraph option does not honor leading whitespace when pasted.

In SmarterMail 16.x when Paragraph type "Code" is selected, if you type text leading whitespace (indentation) is honored. If however you copy a block of code with leading whitespace, the leading whitespace collapsed when it is inserted into the email body, making actual code unreadable.

This annoying for all languages (c, c++, C#, emacs, VB, PL/SQL), but for Python, it renders the code unusable.
