some keyboard keys inaccessible when using focus method

[bkdevteam]

Hello, When i use focus() method i can't press key "^{" anymore, thus i can't type "ô", "ê" etc... It is only when the focus is automatic, if i focus manually with mouse it works nicely. That very very weird.}

CKEDITOR.instanceseditor1?.on('instanceReady', function(evt) {

evt.editor.focus();

});

Environnement is MAC OSX with FireFox 16. (Works fine on windows)

I attach an example of freshly downloaded 3.6.5.
