Now that we reset the size of the FrameView and do layout upon every autoSizeIfEnabled, we also need to reset our width to the minimum auto-size width. Previously we were resetting to the FrameView's current width, which is vaguely OK if we only reset it the first time we autosize, but breaks everything (makes minimum width changes not take effect unless the view is forcefully resized) if we reset it every time.
