Webview CSP blocks some htmlwidgets with web workers

[anthonynorth]

Describe the bug
Webview content security policy blocks web workers with blob urls. This prevents some htmlwidgets from rendering correctly (or at all) in the viewer.

Can you fix this issue by yourself? (We appreciate the help)
Yes. It's a 1-liner.

(If yes,) can we assist you with anything?
Let me know if you're ok with these directives for worker-src (which is currently not defined).

worker-src https: data: blob: filesystem:

Thanks for reporting! WebView is known to have some limitation on certain usage of resources. Have you tried it and it actually works for you?

The problem with webview in this instance is that the content-security-policy doesn't allow for blob sources. The linked PR addresses this.
