+Subject: [PATCH] Backport fix for test that started to fail with libxml2
+ 2.10.4
+
+This is a backport of the relevant part of
+91fcb290ab0cc26a8ec584da9610f553fd27ac97 "libxml2: upgrade to release 2.10.4"
+from libreoffice-7-5-3.
+
+I had seen builds of LibreOffice 7.5.2 on Flathub start to fail now after
+<https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/commit/f8fe772fe3134e95d8d0a17a225a0453bbbc1e86>
+"Update elements/components/libxml2.bst to v2.10.4-0", with the same symptoms as
+described for the backported fix, e.g.
+(<https://buildbot.flathub.org/#/builders/26/builds/4650>),
+
+> xmltesttools.cxx:188:Assertion
+> Test name: testReqIfTable::Import_Export
+> equality assertion failed
+> - Expected: 1
+> - Actual  : 0
+> - In <file:///tmp/lu6859867e7nps.tmp>, XPath '/html/body/div/table/tr/th' number of nodes is incorrect
+> Failures !!!
+> Run: 81   Failure total: 1   Failures: 1   Errors: 0
+> Error: a unit test failed, please do one of:
+> make CppunitTest_sw_htmlexport CPPUNITTRACE="gdb --args"
+>     # for interactive debugging on Linux
+> make CppunitTest_sw_htmlexport VALGRIND=memcheck
+>     # for memory checking
+> make CppunitTest_sw_htmlexport DEBUGCPPUNIT=TRUE
+>     # for exception catching
+> You can limit the execution to just one particular test by:
+> make CPPUNIT_TEST_NAME="testXYZ" ...above mentioned params...
+> make[1]: *** [/run/build/libreoffice/solenv/gbuild/CppunitTest.mk:121: /run/build/libreoffice/workdir/CppunitTest/sw_htmlexport.test] Error 1
