Steps to reproduce:

1. Open https://jsbin.com/tawelomajo/1/edit?html,js,output by iPad (not iPhone) Safari.
2. Touch the select box. Change the value to "2" on shown popup UI.
3. Re-touch the select box.

Expected behavior:

Both of them should be "1":
- the displayed value on HTML
- the default value in popup UI shown by step 3.

Actual behavior:

The displayed value on HTML is "1", but the default value in popup UI is "2".
The latter will be fixed when the <select> loses focus by touching anywhere or calling "blur()".

Note:

All browsers other than iPad Safari works correctly.
On iPhone Safari, the <select> automatically loses focus after changing value so the issue cannot be reproduced.
