User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20180128191252

Steps to reproduce:

Create a <select multiple="multiple"> element and create multiple options with some having the same "value" field. When selecting any number of these options (either by clicking or by adding selected="selected"), upon refresh all options sharing the same values as those selected will be selected.


Actual results:

All options sharing the same values as the previously selected options are selected on refresh.


Expected results:

The previous selections should be cleared on refresh for all options manually selected (e.g. mouse click), otherwise the options with selected="selected" should be selected on refresh.
