Details for the issue

With current master head (98c9b3b), there appears to be some problems with selecting columns in the Browse Data tab.

1. When clicking a column header (a normal click, not especially long), the column is sorted (as expected). To select an individual column, it seems like doing a rectangle selection over the column header works, or even a long click + small mouse move... but, when the mouse click (doing the selection) is released, our column sorting code catches it and the column is then sorted.

So, the selection area holds, but the rows are now in a different order.

2. Similar to above, but when doing a rectangle selection for multiple columns. When the mouse click is released from the final column, which column it was over then catches the mouse release event, so that column then gets sorted.

What should happen, is our code should recognise a selection operation is in place + not generate a column sort from it. 😄

Haven't checked if this happens in 3.11.0 series yet.
