bootstrap 带文本区域的弹出窗口：无法水平调整大小

Question

当文本区域位于 bootstrap 弹出框内时，我无法通过拖动调整其宽度：

或者在代码中：

<button id="popoverBtn" type="button" class="btn btn-lg btn-danger">
Click to toggle popover
</button>

$(function () {
  $('#popoverBtn').popover({
    'title': 'this is a textarea test with a long title',
    html: true,
    trigger: 'click hover',
    content: document.createElement('textarea')
  });
})

奇怪的是，我没有发现任何描述此类行为的已知问题。这种行为的原因可能是什么？

感谢您的帮助！

Strangely, I haven't found any known issues describing such a behavior. What could be the reason for this behavior?

答案在Bootstrap documentation

textarea's are modified to only be resizable vertically as horizontal resizing often “breaks” page layout.

可以通过指定 resize:"both" 和显式 maxWidth 来覆盖这种行为，以防止 textarea 与父容器重叠，如下所示：

$(function () {
  $('#popoverBtn').popover({
    'title': 'this is a textarea test with a long title',
    html: true,
    trigger: 'click hover',
    content: createContent()
  })
  .on("show.bs.popover", function() {
    const parentEl = $(this).data("bs.popover").getTipElement();
  });
})


function createContent(){
   var textArea = $('<textarea class="textarea-resiable" />'); 
   textArea.css({resize:"both",maxWidth: '250px'});
   return textArea;
}
