IPhone UIWebView width does not fit after zooming + orientation change

Question

I created a bare bones iPhone/iPad app with a UIWebView (Scales Page to Fit = YES, shouldAutorotateToInterfaceOrientation = YES) and loaded a webpage, e.g. http://stackoverflow.com/
- (void)viewDidLoad {
[super viewDidLoad];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://stackoverflow.com/"]];
[webview loadRequest:request];
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
The web page fits the width nicely. Rotate the device, the webpage continues to fit the width nicely. Good.
Incorrect: Zoom into the page and zoom out. Now rotating the device shows UIWebView in a weird width in one of the orientation (if u zoom in+out landscape, the portrait width becomes weird, vice versa). This behavior is fixed only after you navigate to another page (or [webview reload]).
Correct: Load the same URL in *Mobile Safari* on the same device. Rotating works & the width always fits properly, regardless of the zooming interaction.
Is this a UIWebView bug (probably not)? Or is there something that needs to be done to make things "just work" like in Mobile Safari?
This behavior exists on iPhone and iPad
