Selection state of F-Curves is lost when resizing the Graph Editor. The problem was that SIPO_TEMP_NEEDCHANSYNC was getting set in the graph_init() callback, which gets called everytime the view resizes, and not just the very first time this happens. However, setting this flag forces the selection state to the updated/pulled from the scene data. In the past, it was necessary to set this flag so that we could force F-Curve colors to get initialised correctly. However, things probably changed at some point, so this behaviour is no longer needed. At worst now, opening a new graph editor may not show F-Curve selection correctly synced with the viewport, though that's easily worked around by reselecting whatever it is in the 3d view.
