Moving item on Windows not working

[richboss]

Describe the bug
According to documentation, an item can be moved from one tab to another by dragging it with the mouse (without pressing any modifier key). This does not work correctly on Windows. On Windows the item gets copied to the destination tab, but it will not be removed from the source tab, hence effectively getting duplicated on the destination tab. On Linux, for comparison, it works as expected.

To Reproduce
Steps to reproduce the behavior:

1. Create an item with arbitrary content on any tab (e.g. the default "Clipboard" tab)
2. Create a second tab
3. Use the mouse to drag the item to the second tab
4. Observe that the item gets copied to the second tab, but at the same time remains on the first tab.

Expected behavior
The item should be moved, not copied.
