Optional change, but this could be shortened to const { messageHandler, loadingTask, } = this; instead.

Can't you use loadingTask as defined in the surrounding scope, both here and on the next line?

I assuming that you've already checked, but otherwise please make sure that Webpack/Babel is able to convert this into code compatible with older browsers. (Note that I'm expecting this to "just work" given this option).

Good point. I found that babel-present-env fortunately includes the exponentiation operator plugin (see https://github.com/babel/babel/blob/master/packages/babel-preset-env/package.json#L36), so that should be fine.

If you include something along these lines e59f952, then you ought to be able to use for...of instead here:
for (const flag of PermissionFlag) {
if (flags & flag) {
...

I tried this and unfortunately it doesn't work. Objects, unlike other data structures such as Maps, are not iterable in JavaScript. According to https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/is_not_iterable there are some other ways to do this but I don't think it's much more readable.

I totally overlooked that it's an Object, sorry about wasting your time here.

Here, and elsewhere below, the slightly less verbose }).catch(done.fail); ought to work.

Fixes #9972.
@Snuffleupagus Would you be willing to review this if you have time? I recommend to review this per commit and with the
?w=1flag. For some reason the?w=1flag doesn't seem to work on GitHub for the second commit, but it does locally if you usegit show HEAD~1 --ignore-all-spacewith this branch checked out.
