Subject: [PATCH] Handle tags with uppercased 'sizes' attr

Some web sources contains tags like:
```xml
<link data-react-helmet="true" href="/public/favicons/color-1.ico" rel="shortcut icon" sizes="192X192" type="image/x-icon"/>
```
In order to handle them correctly it's necessary to ignore the 'sizes' attribute case while resolving the dimensions
