titlesec makes fancyhdr mistreating the document class


How to use short subsection title in header but not in table of contents?Book fancyhdr confusionCreate a document cover using style classUsing titlesec to have chaptertitle and sectiontitle in twosided reportFancyhdr - No “Chapter” Word, but part numberInsert the number and name of the section in the header, (including on a chapter's opening page)How to automatically generate names of sections in head part of fancyhdr?Put the section and subsection in headers using fancyhdrProblem with fancyhdr aligned text and showDefining a New pagestyle Using Fancyhdr

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?
