I know that this change is not related to this particular issue, but it's pretty
small, and I would have had to either use `let` for the platform import to be
consistent with this module, or `const` to be consistent with the rest of the
code. So I choose to be consistent with the rest of the code and updated this
import as well. 

[Sebastian Noack, 2018/09/06 13:43:21]

I agree, but while on it, it also seems unnecessary to wrap this line.

[geo, 2018/09/06 20:10:47]

You're right. I was so focused on that let and const, that I didn't even
noticed. Thank you!

Nit: It might read better with a blank line above.

[geo, 2018/09/06 20:10:47]

Done.

[Sebastian Noack, 2018/09/06 13:43:21]

Can we link to the Microsoft Edge bugs directly, rather than the issue in our
issue tracker?

Done.
