Description

Add more async processing in the validation code paths to ensure that cancellation can be triggered.

Repro in VS Code language service extension

  • open large section document
  • incrementally modify the file near the bottom, keeping it in a valid parser state as often as possible
  • check the Power Query output window to see that diagnostics processing is not being cancelled
