 Another case where a single DOM node is represented by multiple frames is when a text node contains bidirectional text (e.g. both Hebrew and English text). In this case, the text node and its inline ancestors are split so that each frame contains only unidirectional text.
-The first frame for an element is called the primary frame. The other frames are called continuation frames. Primary frames are created by nsCSSFrameConstructor in response to content insertion notifications. Continuation frames are created during bidi resulution, and during reflow, when reflow detects that a content element cannot be fully laid out within the constraints assigned (e.g., when inline text will not fit within a particular width constraint, or when a block cannot be laid out within a particular height constraint).

 Continuation frames created during reflow are called "fluid" continuations (or "in-flows"). Other continuation frames (currently, those created during bidi resolution), are, in contrast, "non-fluid". The NS_FRAME_IS_FLUID_CONTINUATION state bit indicates whether a continuation frame is fluid or not.
