Degrade to fallback WebView on error

[kiftio]

What are you trying to accomplish?

Work in progress

• Fallback to a simple WebView onError. To avoid running into the same issue that caused the error in the main WebView, the fallback WebView will not:
  • add the sheet kit User-Agent
  • add a JavaScript interface / the bridge
  • override link clicks
  • send instrumentation
  • be cached
• Allow client so disable the fallback behaviour via configuration
• Allow clients to perform actions before fallback (e.g. cookie cleanup if deemed necessary)

Before you deploy

• [ ] I have added tests to support my implementation
• [ ] I have read and agree with the contributing documentation
• [ ] I have read and agree with the code of conduct documentation
• [ ] I have updated the README (if applicable).
