SUMMARY
In KTextEditor-based editors (tried Kate, KWrite, KDevelop) when dragging selected text, the dragged text is shown near the mouse cursor. However, if word-wrap is enabled and there are some wrapped lines above the selection, the location of the dragged text is wrong. If the selected text is across multiple lines involving automatically wrapped lines, the content of the displayed text is wrong as well.

It's best explained with a screen recording.
