ExtJS 3.4: Ext.util.CSS.getRule Issue in IE8

Ext.util.CSS.getRule doesn't appear to work in IE8 but it works in chrome.

My CSS

Code:

---

.x_3FieldsPerLine input, .x_3FieldsPerLine select {
    width: 227px;
}

---

My ExtJS

Code:

---

var classCssRule = Ext.util.CSS.getRule(".x_3FieldsPerLine input, .x_3FieldsPerLine select");       
var cssWidth = classCssRule.style.width;

---

classCssRule appears to be undefined in IE8 although in chrome it is object and cssWidth is 227px

Thanks for the report! I have opened a bug in our bug tracker.

Just an update if I add new css rules like below and call Ext.util.CSS.getRule(".x_3FieldsPerLine") it works

Code:

---

.x_3FieldsPerLine {
    width: 227px;
}
