            Bug ID: 20847
           Summary: Ignoring direction of the cue text when positioning

According to the third step of the rendering rules, the direction parameter is
determined based on the cue text contents by applying the Unicode Bidirectional

Depending on the text direction, the cue is positioned differently within the
video element with the same cue settings.

An use case of not changing the final positioned cue with respect to the
determined language are translated captions.

For example, if the cue was positioned in a specific part of the video as to
not occlude visual elements of the video, this would allow the translated
caption to preserve this property if the final position is not changed.

Adding a setting that would override the default language dependent behavior
would allow caption translators and automatic services to have no knowledge
about the different positioning schemes of the cue (and not require to reverse
engineer the original position).
