Describe the solution you'd like
Forward autofocus property to actual shadowed input

look up the shadowed input programmatically and call its focus method

Thanks for the report! Looks like autofocus attribute on the input should just work (Example: https://glitch.com/edit/#!/humane-bramble-bunny)

Isn't the question here how to autofocus mwc-textfield?
The Glitch demo merely puts autofocus on a native input element.
