* Use plain text rather than HTML in TextNode ** Bypasses HTML parsing, and doesn't cause regeneration of nodes like appending to .innerHTML does ** We were only using HTML so we could use entities, so replace those with \uNNNN sequences * Use native DOM functionality rather than jQuery * Inline flushBuffer() Change-Id: I7c6376b55cc0f1420a01a77b365b073fe1636263
