Display problem of ExtJS 2.2.1 grid control in ie6_extjs

As shown below:

The Menuitem icon covers the top of the text. This display effect is very unpleasant.

Looking at the previous version (2.2), I found that this problem does not exist.

So, comparing the two versions 2.2.1 and 2.2, we found that there are differences in the related styles of resources/css/ext-all.css, as shown below:

This problem can be solved by modifying these two styles in version 2.2.1. After modification, it can be displayed normally on IE6, as shown below:

In addition, it can also be displayed normally in opera9.5 and Firefox3.0.10.

The latest 3.0 RC1 version of ExtJS no longer has this problem.
