ie7 Style Attributes don't register

[megawac]

Quirksmode calls .attributes compat "A bloody mess." We use indexed attributes (relevant section)... Here's some highlights of problems to address

• Do yourself a favour and don't use the indexed attributes array.
• IE7 and lower don't return the value of a style attribute.
• IE 5.5 doesn't return custom attributes, and initially gives the attribute value instead of an attribute object.
• IE7 and lower give null for style values.
• IE 5.5 initially gives the value of the attribute; not the attribute object.

//Issue
var attributeTest = document.createElement("i");
attributeTest.style.width = "140px";
attributeTest.attributes.style.value ~~ "width: 140px;" //normally (browser dependent case, semi etc)
//ie<7
attributeTest.attributes.style.value === "null" //shit...

Hacky solution:

Replace this equality test with something like

if (attr.value !== $oldstate[name] || 
    //handle ie7 inline style attribute
    (attr.name === "style" && attr.value != "null" &&
        $target.outerHTML.match(/style=["'].*["']/)[0] !== $oldstate[name]
    )
)
