test case

text-align: start fails inside a <th>; the content in the cell is centred aligned instead (the default / initial value)
text-align: end fails inside a <td>; text is left-aligned instead (text-align: start appears to work, but then, text-align: left is the initial value…)

In the attached test case, I’ve set `td { text-align: center; }` this is (correctly) overridden by `text-align: start`.

Tested on 10.10.2 with Safari 8.0.3 and latest Nightly build (r179862)

This is still relevant.

This works as expected in Chrome and Firefox.

You need to reduce styleTypePadding by one so since you are grabbing bit there. It would also be clearer to add hasExplicitlySetTextAlignOffset bit to the beginning of the byte 7 so that the padding stays at end.
