Throwing exception when using Medium.insertHtml

[samfriend]

medium.js Uncaught TypeError: Cannot read property 'length' of null

if i type this in browser console
medium.insertHtml('123456');
it throws error

if i trigger this from a button click, it works

[samfriend]

what is Medium.activeElement for?

the insert() method needs Medium.activeElement === this.medium.element

but if i call from console or other class (e.g. fileupload) , the activeElement is null thus throws error

focus() method also wont set the activeElement
