It looks like the grid believes we are pre-layout (meaning that we are in the preferred width computation phase). Either some hasDirtyPreferredWidth bits got lost or the grid was not laid out the first place (was not dirty) and we are laying it out now. Anyway that's why we need a test reduction so that we can debug this in a comprehensible context.
