Using a stunt webserver which artificially introduces a 3s delay just before the last line of the HTML output, I have reproduced a uwer-reported loading/startup race bug: Previously the wasm loading was started by the <script> element, synchronously. If the wasm loading is fast, and finishes before the HTML loading, the onRuntimeInitialized event may occur before initPuzzles. But initPuzzles sets up the event handler. Fix this bug, and introduce a new comment containing an argument for the correctness of the new approach. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
