Fixes the assertion failure with text: "###!!! ASSERTION: Wrong line container hint: '!aForFrame || (aLineContainer == FindLineContainer(aForFrame) || aLineContainer->GetType() == nsGkAtoms::rubyTextContainerFrame || (aLineContainer->GetType() == nsGkAtoms::letterFrame && aLineContainer->IsFloating()))', file /home/sgbowen/builds/mozilla-central/layout/generic/nsTextFrame.cpp, line 1259" which occasionally appears when opening pages with ruby or when running ruby reftests. Updates the manifest for ruby reftests to the current expectations (adjust assertion counts, etc.)
