Some Items won't be tagged from dragging and dropping items in tag to another

@ag_preet

I created a [test] tag and tried moving all the items at once to that additional tag and 2 were not tagged properly.
One was a Login, the other one was also a login but its website was "app://xxxx". No custom icons were added to items.

Selecting only a few works every time (although I've only done this a couple of times).

Then I created a [new test] tag, this time several different items were being left out. One was a Note, the others were all Logins.

This is so random and all I can tell you is if you select all items in one tag and you wish to move to another tag by drag-and-drop, some items (probably the last few ones) will always be left out.

Please please look into this and hopefully a fix will be implemented.
