If `org-src-preserve-indentation' is nil, then embedded (not just 
leading/trailing) tabs in src blocks are converted to spaces when 
`org-edit-src-code' is called or when exported. Not sure I would call this 
a bug.

If that is not deemed a bug, the docstring needs to mention that embedded 
tabs get converted.

Apart from that, the documentation needs to reverse this in 14.2:

"may replace sequences of spaces with tab characters"

as it is spaces that replace tab characters.

Best,
