Title tag text disappearing in Alpha 4

Title tag text disappearing in Alpha 4

In switching from alpha 3 to 4 today, I noticed that when testing in Firefox (3.6.16), the title for my mobile site isn't showing up in the Firefox tab anymore.

Confirming that the title has disappeared, I tried saving the page to my home screen on my iPod Touch (the most recent release with retina display). When saving to the homescreen, iOS uses that title tag as the name for the app icon. Just like in Firefox, that field was now blank.

In alpha 3, both the Firefox tab and the app icon title work fine.

Did I miss something?
