Fix activeElement check #193

Closes #193

[danez]

checking for typeof unknown seems weird to me as this is not really somewhere in the spec. I would think it is more clear what the intend is if we do the same fix that vue did: vuejs/vue@fc3d7cd

Do you think that would work? Also please add a comment to the code so we know why we do this.

Sure thing, I'll reimplement similar to vuejs/vue@fc3d7cd and add a comment for context.

The most recent PR failed because the catch block is empty (caught in eslint rules). Is there something you'd prefer be done in the catch block?

Or, I could update the try to instead evaluate if typeof document.activeElement resolves to an 'object'.

var activeElementAvailable = typeof document.activeElement === 'object';
