Fix timeline markers not working on Chrome (#13887)

* Periodically save timeline markers

This saves timeline markers immediately upon message arrival, but not more
than once every 5 minutes.

This does not change how the markers are saved on closing the window,
except that it avoids submitting them if there is no need for it.

* Use the Fetch API when possible instead of XHR on window unload
