Pro 3.0 comes with a great new feature that warns you when you're about to run a tool or other process on a selection. However, the warning is appearing somewhere it shouldn't: the select by panes when the selection type is set to "New selection." By nature, new selection clears your existing selection, so the warning is erroneous and misleading. In the below example, even though I have two blocks selected, the query clears it, so the warning is not necessary, confusing even.
