Running into some issues with Monaco v0.9.0 >=

Hi,

I'm running into some issues with Monaco:

errors.ts:84 Uncaught Error: TypeError: Cannot read property 'startLineNumber' of undefined

This occurs if I type anything into Monaco. I encounter errors with Monaco versions 0.13.1 to 0.9.0. Monaco version 0.8.3 works fine, however.
