Cursor occasionally gets stuck in drag mode

[testing_things]

Sometimes dragging something in Chrome or Firefox results in the draggable item being stuck to the cursor.

This is a video of the issue: https://emalm.com/?v=DsBSK

Steps to reproduce:

1. Go to google.com
2. Click the Google logo, move the logo as little as possible but enough to cause dragging and then release as soon as possible after you see that your mouse started dragging. Try doing it very quickly like in the video: https://emalm.com/?v=DsBSK
3. Sometimes the cursor would get stuck in the drag mode with the Google logo attached to it (even though the mouse button is no longer pressed).
