[LH2977] Moving a document causes outliner column resize

When I move a document up or down (Ctrl-Up / Ctrl-Down) the Title column width in the outline view reduces.
Happens if the move takes place in the binder or the outliner. Only seems to affect the title column.
Occurs in 2.9.0.4 build beta, (149671).
