NW2: window blur event does not execute multiple event listeners

[bastimeyer]

NWJS Version: tested with 0.45.5 and 0.46.0
Operating System: Arch Linux with KDE Plasma

Description

The window blur event on the new NW2 implementation has already received a bugfix in #7327, but when adding multiple event listeners, all listeners except the first one get ignored.

When disabling NW2 in the chromium-args field, the issue does not occur.

How to reproduce

See my bug demonstration here:
https://github.com/bastimeyer/nwjs-blur-event-bug

In the dev-tools console you'll see that only "blur 1" gets logged, whereas the focus event works as expected and logs "focus 1" and "focus 2".

This is fixed in git and will be available in the next nightly build.
