Build ID: 20160502172042

Steps to reproduce:

1 - create test.html with following content :
<html>
<body>
<select>
	<option>Hello</option>
	<option>World</option>
</select>
</body>
</html>
2 - Open the page in Firefox browser
3 - Modify test.html with content :
<html>
<body>
<select>
	<option>Hello</option>
	<option selected="">World</option>
</select>
</body>
</html>
- Refresh page in browser by pressing F5



Actual results:

Selected option has not changed in select box, it's still "Hello". Its only displaying "World" when refreshing the page with Ctrl + R


Expected results:

Selected option should have changed in select box, it should be "World"
I can confirm this issue on the latest Nightly 50.0a1 (Build ID: 20160612030220).

Still present in FF 98.0.1 (64-bit).
This bug made me change the status of a long list of products status, since a new product was added in the list, but the combos kept old values based on the position of the original list.
Not a logic failure.

This is the HTML code in developer console

<tr class="disabled">
     <td><img src="48092.jpg" width="30"></td>
     <td>Cast Sage</td>
     <td>48092</td>
     <td>110</td>
     <td>0</td>
     <td>
           <select name="color_overrides[807]" style="visibility: visible;">
                <option value="">No Override</option>
                <option value="yes">Always Enabled</option>
                <option value="no" selected="">Always Disabled</option>
           </select>
     </td>
</tr>

And the combo shows "No Override", since it was the value of the nth-1 combo before hitting F5.
If Ctrl + F5 is pressed, everything works as expected.

Yes, this is expected. Alternatively you can use autocomplete="off" in the select. This is a form restoration issue, not a layout issue. But I think it's WONTFIX tbh.
