titlesec makes fancyhdr mistreating the document class
MWE is pretty simple:
documentclass[twoside]{article}
%usepackage{titlesec}
usepackage{fancyhdr}
begin{document}
pagestyle{fancy}
section{tist1}
subsection{a}
newpage
subsection{b}
end{document}
On the second page, there is the subsection name on the left and the section name on the right.
Now, uncomment the titlesec import, and the behaviour changes: the section name on the left and nothing (actually, a fantom of non-existent chapter name) on the right.
It happens because titlesec redefines chapter as relax, though normally it's undefined in article class. The fancyhdr packages has a following check:
ifxchapter@undefined
It fails, and marks are defined as in classes that have chapters. I can work it around with
letchapterundefined
after usepackage{titlesec}, or by explicitly redefining sectionmark/subsectionmark after pagestyle{fancy}. But why should I? Is this a bug in titlesec, or setting chapter to relax has some purpose?
UPD:

What versions of the packages are you using? (Putlistfilesbeforedocumentclassand report the output here.) I get identical output with or withouttitlesec.
