More than one bug, I am afraid.

Sure, make sure that the whitespace in the `> <' below is a TAB
character (C-q C-i). Running the src block replaces the TAB when
`org-src-preserve-indentation' is nil.
Also, use `org-edit-src-code' with point in the block and immediately exist,
i.e. =C-c ' C-c '=, and the embedded tab disappears.
#+BEGIN_SRC emacs-lisp
"this is a TAB--> <--"
#+END_SRC
`untabify' is called by some functions that honor (in some way)
`org-src-preserve-indentation' which explains some of this. FWIW, here
is a summary of functions that use the variable:
|---------------------------------------+-----------------------+---------------------------|
| function | protect-leading space | effect on tabs |
|---------------------------------------+-----------------------+---------------------------|
| org-babel-exp-process-buffer | yes or no | ignore (+/- to indent) |
| org-export-unravel-code | yes or no | ignore |
| org-element-src-block-interpreter | contents only or not | ignore |
| org-element-example-block-interpreter | contents only or not | ignore |
| org-fixup-indentation | contents only or not | ignore (+/- to indent) |
| org-babel-parse-src-block-match | yes or no | keep or remove |
| org-babel-haskell-export-to-lhs | yes or no | keep or remove |
| org-babel-spec-to-string | yes or no | keep or remove lead+trail |
| org-src--edit-element | yes or no | keep or remove |
| org-edit-src-code | yes or no | keep or remove |
|---------------------------------------+-----------------------+---------------------------|
the '(+/- to indent)' means that leading tabs may be added or removed
with org-metaright and friends. `keep or remove lead+trail' == "keep
or remove leading or trailing TABs only". 'contents only or not' means
there is no effect on `#+BEGIN...' etc.
HTH,
Chuck
