IE7: Start textfield in Numbered List dialog should be a required field

[james c]

Steps to reproduce the defect:

1. Open the Ajax sample in IE7.
2. Create a numbered list containing 3 items.
3. Right click on the list and select Numbered List Properties from the context menu.
4. Change the type to Upper Alpha.
5. Leave the Start field EMPTY.
6. Click OK.

Expected Result: The list should have A, B and C as the numbers.

Actual Result: The list has @, A and B as the numbers.

Note: If the Start textfield is left empty in FF the list starts at 1 as default. If the Start textfield is left empty in IE7 the list starts at 0 as default.

If you enter 0 into the Start textfield in the Numbered List properties dialog instead of leaving it empty and follow the steps described in the test case you still get the result described in the test case i.e. The list has @, A and B as the numbers.

The dialog must not force a default value to "1". If the field is left empty, the "start" attribute must be removed from the list.

Just a note that the issue reported in comment:3 is a pure browser issue that we cannot fix. All we can do is to ensure that CKEditor produces valid HTML.
