In IE, shift-click secondary sorting works, but also selects all items on page.

When shift-clicking on multiple sortable columns in Internet Explorer (I use IE11), text selection occurs as well.

This can be observed by executing the demo in the tutorial within IE:

ui-grid.info/docs/#/tutorial/102_sorting

Chrome works as expected. Haven't tried other browsers.

I'm seeing this too. :(

Kind of hacky, but you can prevent text selection yourself via CSS.

:not(input):not(textarea) {
    user-select: none;
}
