Thread:VisualEditor/Feedback/Problem with using shift+

Hi. I have been using the visual editor for a while on ar Wikipedia, it is very nice and smooth for fast edits. However, I am facing a very strange problem when I need to add some Arabic diacritics known as tashkil; when I press shift+diacritic button (like x, e, or z) the letter I pressed starts to repeat itself endlessly, and it can only be stopped by refreshing the page and wasting the work I have did. Any thoughts?
