[whatwg] Use of 'direction' of canvas element

has the following bullet point:
  # Form a hypothetical infinitely wide CSS line box containing a
  # single inline box containing the text text, with all the
  # properties at their initial values except the 'font' property of
  # the inline element set to font and the 'direction' property of
  # the inline element set to the 'direction' property of the canvas
  # element. [CSS]

This should describe what to do if the canvas element is not in a
document (and therefore has no 'direction').

It should probably fall back to 'ltr' as a last resort.

However, as an intermediate step, it might be worth falling back to
the direction property of the root element (if present) of the
canvas element's ownerDocument.
