I’m not certain what you mean. In the GIF you do end up docking to the bottom, not the right or left.
Apologies, I meant left or bottom. I’m unable to dock it to the top or right. I updated my previous post.
Do you mean dragging an area out of the main window, and then dragging from there outside of that new window? If that is what you mean, then yes that should not do that, looks like a bug to me.
Yes, exactly that. Here’s another gif for clarification.
The cursor appears to get into a weird state in this particular example as well, I haven’t figured out exactly what causes this yet, but after I close the third window, it believes I’m attempting to dock a window and I have to click again to restore the cursor to a normal state.
