dash closes during type when hit the key which is specified as close window shortcut in combination with super key

[Gabor]

I specified super+o to close window, instead of alt+f4
Now, when I open the dash and try to type, when I hit the o key, dash closes.
My workaround is to use uppercase O.
And does not matter what the key is.
