See: http://www.unicode.org/reports/tr9/tr9-15.html#L1
This is in section 3.4, and therefore should be done after line breaking.
However, currently this is implemented by nsBidi::AdjustWSLevels(), which is only called during resolution (i.e., before line breaking).

This came up in the discussion on bug 336408 (see bug 336408 comment #6 and onwards).
This bug, bug 332655, bug 330350 and bug 263359 (and maybe others) are all somewhat related. We need to redesign some of the interaction between bidi resolution/reordering, reflow and line breaking.

It would be good to (at minimum) check in the attached testcase, and also see if more extensive testing is desirable.
