Any plans for adding a paper-input that expands as user types

[cbelden]

We've come across the need for an input element that will auto-grow horizontally as the user types (ie we want to fit the input element to the value). This is for a feature similar to Drive's document edit view where the user can update the name of the document inline:

Are there any plans to implement an input element that accomplishes this? If not, is there a way we can get this to work with existing Polymer components? As of now, we're planning to create our own custom element that implements the technique highlighted in the accepted answer from this stackoverflow post:

The custom component will wrap a paper-input and will place the desired text into a div that's rendered off screen, measure the width of that div, and assign the width to the paper-input.
