It seems like this problem is caused by http://trac.webkit.org/browser/trunk/WebCore/editing/ApplyStyleCommand.cpp#L949 where it obtains removeStart = start.upstream().  Because upstream will respect block elements, we cannot delete span whose end is visually different from the different of div inside of it.

By the way, in investing this problem, I found a weird behavior in applyInlineStyle.

    bool splitEnd = splitTextElementAtEndIfNeeded(start, end);
    if (splitEnd) {
        start = startPosition();
        end = endPosition();
        endDummySpanAncestor = dummySpanAncestorForNode(end.node());
    }

splits an element even when it's not needed.  e.g. <div id="test" style="font-weight: 900;">world</div> was wrapped by style spans and splited to <div id="test" style="font-weight: 900;"><span class="Apple-style-span">w</span><span class="Apple-style-span">orld</span></div>.  I don't think this behavior is intended and may be filed as a bug.
