Mapping default view zoom interface #129
Description
Where a Mapping page block allows for setting minimum and maximum zoom, there are italicized default numbers displayed (0 and 19). When the arrows to increase or decrease the number are clicked, both of them count upwards from 0 (or, rather, the downward arrow just stays at 0).
Can the maximum zoom window instead start from 19 when the arrows are clicked? Which is to say, when you click up, it should stay on 19, and when you click down, it should decrease to 18.
