Previously only the icon of a file could be dragged in the list display
modes, the name label would invoke box select. This made dragging quite
finicky. I've seen this cause quite some frustration, especially when
the file browser is used as a regular editor to drag data from into
other editors.
Instead follow the Outliner (and some other file browsers like the macOS
one): Dragging on empty space invokes box select, dragging on the name
or icon invokes drag & drop of the item.
Note that 1e9564864c and 6da512f0bc were needed to prepare this change.
