Fix the submit button in the post replacement dialog doing nothing in Chrome. When the submit button in a dialog box is clicked, we tried to fire a 'submit' event on the form to submit it. Apparently this no longer works in Chrome. `requestSubmit` is the modern way to programmatically submit a form, but it's not supported by Safari, or by versions of Firefox or Chrome released before 2019-2020. https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/requestSubmit https://caniuse.com/mdn-api_htmlformelement_requestsubmit
