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
%usepackagetitlesec
usepackagefancyhdr
begindocument
pagestylefancy
sectiontist1
subsectiona
newpage
subsectionb
enddocument


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 usepackagetitlesec, or by explicitly redefining sectionmark/subsectionmark after pagestylefancy. But why should I? Is this a bug in titlesec, or setting chapter to relax has some purpose?
