execCommand is asynchronous?

See refined-github/refined-github#6348 (comment)

Maybe it's only Chromium. I wonder if reading field.value immediately after forces a synchronous update.

.focus() might be asynchronous:

FWIW, Chromium's tests for insertText look synchronous: https://chromium.googlesource.com/chromium/blink.git/+/refs/heads/main/LayoutTests/editing/execCommand/insert-text-not-inheriting-block-properties.html

Presumably, an async focus would look something like (not sure what you're want "refocus" handling to be):

async focus(element, {maxWait}) {
  if (document.activeElement === element) return;
  const deferred = pDefer();
  element.addListener("onfocus", () => {
     assert document.activeElement === element;
     deferred.resolve();
  }, {once: true});
  element.focus();
  return deferred.promise;
}

It's kind of unfortunate because the module now is synchronous, but with that I'd have to make every call async. But it looks about right
