Bug - Bridge 15 beta - scrolling in Content pane stalls

Scrolling in the Content pane stalls in details, thumbnail, and list view.

Display a folder with a few hundred items. Click and drag from the first item down so the list dynamically scrolls. At some point (usually with just a few dozen items selected), the scrolling will stop and the list will not scroll any further, thus limiting the number of items that can be selected.

Reproduced on both Mac and Windows, repeatedly. It does happen occasionally on Bridge 12 but not nearly as often and only when selecting hundreds or more items. Scrolling is also much faster in Bridge 12 than 15 beta.
