html demonstrating intermittent failure

We have found basis transcode fail intermittently in Safari 17 TP running on MacOS 13.5.

This appears to be a regression: code and asset is unchanged and runs fine on Chrome, Firefox and Safari 16.

Please find attached a cut-down example. It loads and transcode a single basis file in a webworker using PlayCanvas. The app logs success or failure result to the console.
