SageTeX does not work when TABs are used as indents

Question

I wrote two practically identical files that use SageTeX to determine whether a positive integer is odd or even. The first example uses tabs for indentation.

\documentclass{article}
\usepackage{sagetex}
\begin{document}
\begin{sagesilent}
def oddeven(n):
    if n % 2:
        return "ODD"
    else:
        return "EVEN"
\end{sagesilent}
$3$ is $\sagestr{oddeven(3)}$.
$16$ is $\sagestr{oddeven(16)}$.
\end{document}

Output:

3 is ??.
16 is ??.

Somewhere in the logs:

File "/sagetex_with_tabs.sagetex.sage.py", line 14
    if n % _sage_const_2 :
    ^
IndentationError: expected an indented block

If I change each tab to four spaces, the code compiles without issues and works as expected.

\documentclass{article}
\usepackage{sagetex}
\begin{document}
\begin{sagesilent}
def oddeven(n):
    if n % 2:
        return "ODD"
    else:
        return "EVEN"
\end{sagesilent}
$3$ is $\sagestr{oddeven(3)}$.
$16$ is $\sagestr{oddeven(16)}$.
\end{document}

Output:

3 is ODD.
16 is EVEN.

I have never had issues using tabs for indentation in both Python and LaTeX. It feels very weird that SageTeX does not recognize tabs as a valid method of indentation. How do I get it to recognize tabs?

The following Python code works just fine even though it uses tabs:

def oddeven(n):
    if n % 2:
        return "ODD"
    else:
        return "EVEN"
print("3 is {}.".format(oddeven(3)))
print("16 is {}.".format(oddeven(16)))

p.s. Both tex files were compiled in the following order: pdflatex -> sage -> pdflatex
