As an optimization, FontCascade may render some glyphs to a DisplayList and then replay that list instead of rendering again. But when replaying, the glyphs are not rendered through a GraphicsContext as we would expect, but using FontCascade directly. In the cairo case this means that FontCascade requires a cairo context to render, but if we are in the recording phase of the rendering there's no platform context and we have the crash.
