#1306 Reset pagination if (FE) filter changed (state: open)

We might want to add as an option that the GET parameter for pagination is removed when the filter changes - i.e. when other filter settings are made or the filter is reset.

I don't think it makes much sense to keep the pagination when resetting the filter, for example.

We can install this maybe as an option.

in additional to #1305

Do not need to configure this. Should be the default. Another approach: Only reset pagination if the countItems() differ (prior/after applying the filter)?

but it would be possible to change a filter and randomly get the same number of items - but in my opinion it doesn't make much sense to keep the pagination here
