Buttons on touch devices showing description on single click

Vaadin 7 button on touch devices showing description on single click instead of performing the assigned task. On making the click again its performing the assigned task. (Usually the description is shown on mouse hovering over the component.)

This persist in https://demo.vaadin.com/dashboard/#!dashboard too. There is a ‘Notification’ and ‘Edit Dashboard’ button, only single click using touch device (like Ipad) its showing description of that button instead of performing the assigned task.

Is this the default behavior or there is some workaround for same.

It’s a known issue. This ticket has some workaround possibilities: https://github.com/vaadin/framework/issues/9602
