- Fix: Have export handler, if triggered, always open a window even if no

window name was given (needed in Chrome to avoid opening an extra window)
- Fix (Embedded editor regression): Ensure event handlers are added even if
    document cannot be directly modified
- Enhancement: Add `opts` object to `rasterExport` with `avoidEvent` property
  to avoid calling the `exported` event
- Docs (CHANGES): Update
- Docs (README): Deemphasize unstable embedded editor fixes
