Reviewed by Antti Koivisto.

We should considering breaking position _inside_ the text content when followed 
by (unbreakable) inline box decoration.

 Added.

Added.
* Source/WebCore/layout/formattingContexts/inline/InlineContentBreaker.cpp:
(WebCore::Layout::lastValidBreakingPosition): Add support for cases where the 
next run is not
a text run but an inline box (start/end).
e.g. [inline text item][inline box end] where we should find breaking position 
inside the text and not just return the boundary position between the text and 
the inline box end (which is not a valid breaking position anyway).
