Revision 538198

Fixing a problem with disappearing footnotes inside inlines when hyphenation is enabled, and with disappearing footnotes whose inline child can be hyphenated (quite unlikely, but you never know ...).
As the FootnoteLM was completely "bypassed", it could not add the anchor in the getChangedKnuthElement() phase.
Testcase updated with an example of the "hyphenated inline child" case.
