Steps to Reproduce

Setup:
A Mithril component that renders two different textareas at the same place in the dom tree. This could be a form component that loads different forms depending on the current route.

1. Modify the textarea's value.
2. Click btn "Component 2".

Expected Behavior

The textarea loads the contents "V2"

Observed Behavior

The previous textarea value is shown, instead of "V2".

Context

Need a workaround where the form is padded with empty vnodes so that mithril doesn't consider the textareas being the same element.
