I think the actual result is the intended behavior.
The same thing happens if you for example drag some text
instead:
1. open a text editor
2. focus a Firefox window (such as this bug report)
   (make sure 1 and 2 overlaps partially with 2 on top)
3. select some text in 2, then drag the selected text onto
   the text editor
4. repeat 3 a few times

On Linux, this does NOT raise the text editor window
on top or focus it in step 3.  I would expect dragging
tabs to behave the same.
