Research direction

Start by reproducing the issue in the TopAppBarCollapsingMultilineDemoFragment with Force RTL layout direction enabled, then trace the CollapsingToolbarLayout text rendering and line wrapping. Done means the full stop remains at the end of the LTR sentence rather than appearing at the beginning of the third line.
