Clicking scrollbar in <select multiple> with overflowed options will select nearby <option> in Chrome

I use chrome v50.0.2661.87 m.

While option text overflowed, user could select option every single clicking on scrollbar.

Does anyone could reproduce this issue?

Here is the sample code:

And finally I found if:

```
select > option {
  overflow-x:hidden;
}
```

and problem solved!!!!
