Status > Filter Reload page is confusingly worded
The way the Filter Reload page is displayed implies that the filter rules are loaded by simply visiting the page.
The initially shows:
"This page will automatically refresh every 3 seconds until the filter is done reloading."
then after 3 seconds shows:
"Done. The filter rules have been reloaded".
But the filter rules are not actually reloaded until the button is pressed.
