Opening a select control sends a mouseout event (e) with null as e.relatedTarget whilst Chrome does not. If an event handler depends on the value of e.relatedTarget this can lead to the select misbehaving e.g. automatically closing on open.

I figured this bug could be somewhat related to bug 1882274.

Ah, nevermind, this bug depends on bug 1778923 and edgar is being NI on that bug. I should just let Edgar to deal with this.
