Only check for bound children at the start of the drag/set bar time

Checking for bound children at every mouse move/set bar time change
caused child bars to be added to the drag/time change set if some
intermediate start/end value matched the child bar start/end value.
The document didn't update start/end for these bars, however, leading
to inconsistent state between UI and document.
