• Dragged tab to different tab island. Result: No crash
• Dragged a tab out of window to create a new window. Result: No crash
• Dragged tab into different window, windows side by side, both visible on screen. Result: No crash
• Dragged tab from one full-screen window to another full-screen window. Used alt+tab to switch windows while dragging tab. Result: Crash.

Observed that crash occurs immediately upon alt+tab if actively dragging a tab. Refined tests follow:

• Several repeated attempts to alt+tab. Result: Crash.
• Attempted to use win+tab while dragging tab. Result: Crash.
• Attempted to use alt+tab with two side-by-side windows, rather than two full-screen windows. Result: Crash.
• Same as above, with win+tab. Result: crash.
