I have a mac CEF app that uses off screen rendering and I'm working on drag and drop functionality. I'm heavily borrowing code cefclient, and mostly things are good. However I've noticed a behavior difference between cefclient with and without OSR turned on. Attached below are two screencaps that show the same drag and drop action on this codepen, where I click the "Triumph" div and drag it to the "Your Selection" div on the right: https://codepen.io/notepage/pen/XavXaE The normal (without_osr version) shows that during the drag and drop there's a nice thumbnail of the Triumph div being dragged attached to the cursor. The OSR version of the same action however does not include this thumbnail. I'm at a loss for explaining this difference in behavior, and am failing to find relevant code in cefclient, libcef, and chromium sources. Does anyone know where I might look to see how this drag and drop thumbnail cursor is implemented, or any ideas on how I may implement something similar for the OSR browser in my app?
