Try adding in customizer -> additional CSS

html, body, #main{      

    user-select: auto !important; /* supported by Chrome and Opera */      

    -webkit-user-select: auto !important; /* Safari */      

    -khtml-user-select: auto !important; /* Konqueror HTML */      

    -moz-user-select: auto !important; /* Firefox */
