We measured the ratio $P_{x}/P_{z}$ of the transverse to longitudinalcomponents of polarization transferred from electrons to bound protons in$^{12}\mathrm{C}$ by the $^{12}\mathrm{C}(\vec{e},e'\vec{p})$ process at theMainz Microtron (MAMI). We observed consistent deviations from unity of thisratio normalized to the free-proton ratio,$(P_{x}/P_{z})_{^{12}\mathrm{C}}/(P_{x}/P_{z})_{^{1}\mathrm{H}}$, for both $s$-and $p$-shell knocked out protons, even though they are embedded in averagedlocal densities that differ by about a factor of two. The dependence of thedouble ratio on proton virtuality is similar to the one for knocked out protonsfrom $^{2}\mathrm{H}$ and $^{4}\mathrm{He}$, suggesting a universal behavior.It further implies no dependence on average local nuclear density.
