Since recently, whenever a text-field (e.g. the address bar or the askubuntu search field) is highlighted inside Google Chrome, I cannot use Ubuntu shortcuts (e.g. `Ctrl`+`W` to close a window). When hitting `Ctrl`+`W` nothing happens. As soon as I press tab to leave the text-field, the shortcuts work as expected (e.g. `Ctrl`+`W` closes the window).

I have no idea why this happens. Any ideas how to debug or solve this?

I am using Ubuntu 18.04.1 LTS and Google Chrome 71.0.3578.98.

Edit: It seems that this issue is somehow connect to Keyboard Layouts. Mostly, I use the layout "English (US, intl., with dead Keys)". In this case, the above problem occurs and shortcuts no longer work when text fields are highlighted. When switching to "English (US)", Ctrl + w closes the window as intended, even when a text field is highlighted. (Credit to mr. Pavlikov)
