Description of problem: See this upstream issue: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/8667 Proposing as a Final blocker: "For each release-blocking desktop, the desktop environment must perform regular operations like windows close/resize/maximize/minimize/fullscreen (when supported/applicable), windows switching, using windows on virtual workspaces, and similar common operations as expected. Common application content such as regular application windows, video output, and games must be displayed correctly. " https://fedoraproject.org/wiki/Fedora_43_Final_Release_Criteria#Window_manager_functionality It's not explicitly listed, but dragging a tab into a new window could be considered a common operation. Also, the consequence of this bug is pretty harsh, losing all unsaved work.
AGREED AcceptedFinalBlocker Discussed at the 2025-09-22 (blocker / freeze exception) review meeting: This bug is accepted as a violation of the cited criterion, counting 'drag tab to create a new window' as a "regular operation" for a browser. It is noted that while chromium/chrome is not the default browser in any Fedora edition, they are very widely used so we can expect this bug will be commonly encountered, and the consequence is very bad (full desktop crash). https://meetbot-raw.fedoraproject.org//blocker-review_matrix_fedoraproject-org/2025-09-22/f43-blocker-review.2025-09-22-16.01.txt
