I researched the saveRefreshState() and restoreRefreshState() addition and
it uncovered a bug which then uncovered a problem with how our UI works.
The bug was that the selectedAlerts field (checkboxes in the list) was not
getting cleared on any of the bulk actions. As refreshes happened the
checkboxes would disappear and be replaced by new results but that that field
would constantly grow because they were never unchecked on the previous page.
It was benign before this PR but is now causing a lot of duplicate REST
requests. We need to figure out the right way to clear these when a bulk
action finishes but there is also another issue.
As I was testing for this I realized when I set the refresh rate to a high
rate I had to click quickly or the page would change and I would lose my
selections. What @iraghumitra mentions above is a pause while the REST
requests are being processed but I think it makes sense to pause even earlier,
whenever you have a checkbox checked. I can obviously get it to work if I
pause it but I think that's a better UX.
