(iOS) Infinite Loop when a "NSURLErrorCancelled -999" is received on didFailLoadWithError

**Problem**

Infinite loop in didFailNavigation.

**What is expected to happen?**

Should not infinite loop.

**What does actually happen?**

Infinite loop with failed loads of the error URL.

**Command or Code**

As described. It seemed to depend a bit on timing, so I can't easily provide a code sample that consistently replicated the issue.

**Environment, Platform, Device**

Various different iOS devices and simulators.

this is more prominent on ios 12.4 in my case, interestingly this is working fine on latest os.
