Target: main
  • setDisplayMediaRequestHandler: capture-handle, zoom and cross-session checks are computed against the WebContents that called getDisplayMedia(); previously this could dereference null when granting another tab by id.
  • Passing a WebFrameMain whose frame has been destroyed as video / audio throws a TypeError instead of crashing; a request whose own frame is gone fails cleanly.
  • A WebFrameMain grant captures the tab that contains the frame; the docs now say so and the example only self-captures top-level frames.

Notes: Fixed crashes in setDisplayMediaRequestHandler when the granted frame had been destroyed or another tab was granted by id.
