pcbnew grid selection limited after fast-grid switch

[Seth Hillbrand]

After switching my pcbnew grid using the first Fast-Grid selection hotkey, selecting a different grid size using the right-click context menu doesn't change the grid size. Using hotkeys N, shift-N still works. This persists across restarts and different projects.

Not 100% certain that the fast-grid switch is related.
