Notes not working on webkit

[theotheroracle]

on webkit on login, the loading bar is just loading forever, and in the console there's
[Error] Unrecognized Content-Security-Policy directive 'worker-src'.

i enabled logging and then got the error

undefined is not an object (evaluating 'n.localeCompare')
