ComboBox list grows with mouse over in IE9

[jamesr]

REQUIRED INFORMATION Ext version tested:

• Ext 4.1.3

Browser versions tested against:

• IE9

DOCTYPE tested against: Description:

• For a ComboBox where one of the options contains a single word which is wider than the ComboBox, when expanding the options list, hovering over each option causes the list to grow in size. I've only seen this behaviour in IE9.

Steps to reproduce the problem:

• Either use the attached code snippet or modify the inline example for the Ext.form.field.ComboBox documentation to contain a word wider than the field, eg. 'abcdefghijklmnopqrstuvwxyz'.
• Open the example in IE9
• Click on the trigger to expand the options list
• Hover over the available options

The result that was expected:

• The options list should remain the same height.

The result that occurs instead:

• The option list grows in height as each option is hovered over (see screenshot).

Test Case:

 // The data store containing the list of states
var states = Ext.create('Ext.data.Store', {
    fields: ['abbr', 'name'],
    data : [
        {"abbr":"AL", "name":"abcdefghijklmnopqrstuvwxyz"},
        {"abbr":"AK", "name":"Alaska"},
        {"abbr":"AZ", "name":"Arizona"}
        //...
    ]
});

// Create the combo box, attached to the states data store
Ext.create('Ext.form.ComboBox', {
    fieldLabel: 'Choose State',
    store: states,
    queryMode: 'local',
    displayField: 'name',
    valueField: 'abbr',
    renderTo: Ext.getBody()
});

Thanks for the test case, we already have a bug open for this one: EXTJSIV-7499

Thanks for the quick response. Any idea in which release this is likely to be resolved?
