Sliced Image not expanding like it used to

Hello there,

I just installed the RC2 of Unity 4.6, after working with another version (I believe it was 19 or close to that). After loading up my small test project, I noticed my UI isn't rendering correctly anymore.

Here's how it used to look:



And here's how it looks in RC2:



I didn't change anything in the UI between these two screenshots. Did something change along the way that could justify this behavior? I tried fiddling with the values and properties but nothing so far changed it to what it used to be.

Any ideas? Should I file in a bug? I tried looking both in the forums and in the issue tracker and no one has complained yet, which is why I was a bit skeptical to report this right away.

Thank you for your time!
