jquery ui draggable when set containment draggable div jumping

Question

我正在尝试使用工作正常的jQuery-UI draggable，但我有一个奇怪的行为。当我设置一个收容时，可拖动的div从一侧跳到另一侧。当我禁用它时，我可以顺利地拖动容器。

＆＃13;

＆＃13;

$('.bJS_issueTeaser').draggable({
  'cursor': 'move',
  axis: "x",
  containment: "parent"
});

＆＃13;

.b_ct_issueTeaser {
  width: 37.665rem;
  overflow: hidden;
  max-width: 100%;
  margin-top: 60px;
  position: relative;
  min-height: 250px;
}
.bJS_issueTeaser {
  width: 50.0745rem;
  position: absolute;
}
.row {
  display: flex;
  flex-wrap: wrap;
  margin-left: -0.67rem;
  margin-right: -0.67rem;
}
.c_teaser {
  width: 240px;
  height: 100px;
  padding-left: 0.67rem;
  padding-right: 0.67rem;
}
.c_teaser-inner {
  position: relative;
}
.c_description {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 2rem;
  background: rgba(255, 255, 255, 0.5);
  padding: 0.67rem 1.34rem;
}
.img-fluid {
  display: block;
  max-width: 100%;
  height: auto;
}

＆＃13;
