Description Ali Juma 2019-10-03 13:18:15 PDT 
After the following snippet:

  [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.webkit.org"]]];
  [webView stopLoading];

webView.loading stays YES even though the load has been cancelled, and is never updated back to NO.

PageLoadState has a non-null pendingAPIRequest URL since nothing ever calls PageLoadState::clearPendingAPIRequest

This seems to be because the WebProcess is told to stopLoading after it's already sent the decidePolicyForNavigationAction IPC (which the UIProcess handles in the usual way) but before it receives the policy decision.

Yes, this still happens (tested on iOS 16 beta 2).
