micro_summary: "Script-only `window.open()` was tested for creating an incognito sibling tab, but popup blocking prevented target creation."

scope: "Test script-only `window.open()` from the incognito page."
discard_reason: "Script-only `window.open('about:blank', '_blank')` returned null and produced no new target because popup creation lacked trusted browser user activation."

Attempted path: script-only `window.open('about:blank', '_blank')` from the existing incognito page.
