OK.

I am a bit unsure about setOnBlurHandler
I would like something that is easier to understand and use, but don't have any suggestion on what that would be

I agree, its messy. The whole thing depends on how we handle keyboard nav, either internally in Nebula or externally. And as we don't run a single Nebula instance in embed we need to keep it external (also as we need the sheet to control the ordering of the charts when tabbing/navigating). There might be a combined way we can simplify things, Lihn is fighting it.
But I think we can go ahead with this one for now.

@linhnguyen-qlik think you can merge when you are satisfied, we'll need to continue tinker with parts of this anyways.

@Caele The strange thing is that boxplot doesn't have definition.ext but in production it could still toggleViewData. Just comment here so we don't forget to check this out. I am going to merge this for now.
