Not for me, i just checked again. I can drag what appears to be a thumbnail and it doesn’t behave like a window so i can’t snap it to the side or the grid, and the window is still there so even if there are no other tabs in that window i can’t move the tab to merge with a window below as it’s covered by the first window.
I know I’m a tab juggler 🤹♂️
Imagine asking chatgpt and it tells you to “Google it”
