Why is this change required?
The flaky system test was due to the fact that we had to poll for the
user preferences interface page to reload after saving. However, this
turns out to be a bug on the user perferences interface page because the
page should only reload if the user has selected a new theme that is
different from the site's default but we were reloading the page for
users that did not have any user theme selected. Therefore there was an
unnecessary reload happening when saving other fields on the user
preferences interface page.
Fixes broken behaviour of arrow buttons for certain users as the interval to scroll menu can be cancelled before the scrolling actually happens.
