Highlighting due to click and drag

[PierreRochard]

If you click and drag to increase the crop size past the canvas' edge then it starts highlighting text.

This is not a cropper issue. Please add this to your CSS: body{

-webkit-touch-callout: none; /* iOS Safari */
-webkit-user-select: none; /* Safari */
-khtml-user-select: none; /* Konqueror HTML */
-moz-user-select: none; /* Firefox */
-ms-user-select: none; /* Internet Explorer/Edge */
user-select: none; /* Non-prefixed version, currently
                              supported by Chrome and Opera */

}
