Progressive loader won't load earlier dates

When we drag back the timeline, the previous block never loads.
i just inverse the > in < on line 136-137 in progessive.js
and it works now ^^

           // are we close enough to load the previous block, and is
it loaded?
           if (prevBlockTime < band.getMinDate().getTime() &&
               (!dataMinDate || prevBlockTime <
dataMinDate.getTime()) &&
               !loaded[currBlock - 1]) {
               // load previous block
               // console.log("loading prev block (" + (currBlock -
1)  + ")");
               loader.load(dataset, callback, new
Date(prevBlockTime), currBlock - 1);
           }
