Sortable doesn't work inside of CSS container (container queries)

In my project I use simple layout structure:

<div class="layout">
  <div class="sidebar">....menu....</div> <!-- cca 200px wide -->
  <div class="content">
    <div class="my-sortable-component-is-here">...</div>
  </div>
</div>

If I add container query CSS property "container-type: inline-size" to .content it breaks jQuery UI sortable behaviour. If I drag an item from the sortable div, the item immediately jumps some distance from the position of grab. The shift is probably the same distance as offset of div.content from the top left corner of the document. There is obviously a problem with calculation of position of dragged ghost element (displaced).

.content {
  container-type: inline-size;  /* This is problematic */
}

Reproduce the reported layout with a .content element using container-type: inline-size and a jQuery UI sortable component inside it. Start at the sortable drag behavior and inspect how the displaced ghost element's position is calculated; done means dragging no longer jumps by the content element's document offset.
