Steps to reproduce

The spec was recently changed in regard to how the setters on input.value and textarea.value affect these properties in

Web platform tests for that change are available at

However those web platform tests fail drastically in Edge as it appears Edge’s implementation of those properties is pretty out of whack in the first place. Probably there are other web platform tests in the sibling directory that you could benefit from.

    • Repro of textarea’s selectionStart behaving differently in Edge compared to Firefox and Chrome:

      Edge gets 0 for selectionStart whereas Firefox and Chrome get 11 (the length of the value in the textarea).
