tdf#107126 sw: fix layout crash with section in footnote
SwContentFrame::WouldFit_() contains a hack to temporarily reparent a
SwTextFrame. In the bugdoc, there is a SwTextFrame below a
SwSectionFrame below a SwFootnoteFrame. The reparenting ignores the
SwSectionFrame so the result is a SwTextFrame below SwFootnoteFrame, but
it still has its mbInfSct set, hence crashes with a null pointer.
If the SwTextFrame is permanently moved later on, in
SwFlowFrame::MoveBwd() line 2450 a new SwSectionFrame is created.
