Description

From https://github.com/w3c/web-platform-tests/pull/2589#issuecomment-187208381

What would be useful to test step 3 of https://html.spec.whatwg.org/multipage/forms.html#input-type-change is something like this http://software.hixie.ch/utilities/js/live-dom-viewer/saved/3912

WebKit and Blink fail this, Gecko passes.

Research direction
Investigate the referenced spec step (https://html.spec.whatwg.org/multipage/forms.html#input type change) and the live DOM viewer example (http://software.hixie.ch/utilities/js/live dom viewer/saved/3912). Implement a test that changes input type from text to file and back to text, checking the behavior as described. The test should be added to the appropriate location in the wpt repository. There are prior discussions in the linked PR #2589 comment that may provide guidance.
