Space Logo resized by Confluence

Confluence scales our space logo - without displaying the size used or informing the user what will happen with their company logo (I'm assuming that's what most people use this space for). JIRA allows the admin to set the height and width, however, it is only the admin who can change the logo. This would be really annoying for the person maintaining an internal brand. Worst of all is that the scaled image looks awful! Why is this so? Can we fix it?

Workaround:
You can set the logo size adding this CSS code to your custom space/global stylesheets":

img.global {  
   height:300px;  
   width:200px;  
}  
h1.pagetitle img {  
     max-height:300px;  /* Should be the same than the previous height */  
}
