[css3-text] word-break vs line-break

Although word-break property vs line-break property is conflict the
function for breaking per line, which property is high priority?

Ex 1. Should we break all characters by work-break: break-all?
(should we ignore line-break?)

div {
  word-break: break-all;
  line-break: strict;
}

Ex 2. Should we don't break CJK characters by word-break: keep-all?
(should we ignore line-break?)

div {
  word-break: keep-all;
  line-break: loose;
}
