Search the entire subtree when looking for the end of an inline continuation chain.

Search the entire subtree when looking for the end of an inline continuation chain.

Inlines may be nested, so we may not find the last inline in the chain as a
direct child of the anonymous blocks. We need to search the entire subtree.
Don't do this with anonymous blocks that wrap block children (the block-level
DOM children of the inline-level objects), though. We're not going to find
anything interesting there.

This fix is speculative; the original bug report didn't come with a test case.
