Chrome Version: 73.0.3662.0
OS: Chrome

What steps will reproduce the problem?
(1) Go to Chrome settings
(2) Change language ordering preferences (e.g. move a language to the top).
(3) Restart

What is the expected result?
On a web page, the javascript object "navigator.languages" should reflect the ordering in the settings.

What happens instead?
It reflects the old ordering.

For an example of this bug, see the Chrome canvas app, which uses navigator.languages, but changing the languages do not update the app's language.
