I have a collection selected in My Library. This collection does not contain any items, but the child collections have a total of about 2500 items (I am using recursive collections.)

I am going through this long item list and adding tags. When I add a tag to an item, the list scrolls after the tag has been added so that the selected item is not any more in the visible area of the list. The scrolling can happen into both directions with no apparent pattern. This happens most of the time, but not always. It does not matter whether I add the tag by dragging the item on the tag cloud or by adding the tag using the right pane.

I can provide a screen recording if needed.
