Ie10 can't reproduce online. When the select selector has the function of deleting and selecting and multi selecting at the same time, ie10 will have a bug that the search box can't be input

What is Expected?

It is expected that under IE10, the select selector can use the functions of multiple selection and deletion at the same time.

What is actually happening?

Under ie10, the select selector cannot use multiple selection and delete selection functions normally at the same time.
