Details

According to the spec [1] step4, it requires us to search whole 2D space in order to find a proper place to place a cue without having a overlap with other cues. However, it's too expensive to do that and it won't give us equivalent benefit, the way which we have been using is acutally good enough to handle such a cue overlapping.

So the reason we filed this bug is in case someday we would like to change our mind and decide to follow the spec for arranging cues.
