Template editor - properties input areas have the wrong size

In order to see this, maximize the browser.

• Log as an admin in quickstart
• Go To the documents > Configuration > hippo:namespace > defaultcontent and Edit Article
• Highlight Title
• Locate the splitter and move it leftwards to give lots of space to the Fields and Properties area
• The Property size should be empty so go ahead and type as much as possible until you observe that the text entered never displays beyond some invisible border (see invisible_border.png)

Note that the same goes for the other fields and on IE7, IE8 and Fx 3.6.

Maybe related, else I'll make a separate report, when it comes to Fx the behavior is even more strange because it seems like the text entered goes beyond the area delimited by the input field (see beyond_border.png)
