The input urls generated by the fuzzer can be problematic as it causes very long parse times

Describe the bug

I performed fuzzing for rust-url using afl.rs in the following way.

cargo new --bin url-fuzz-target
cd url-fuzz-target
cargo afl build

While performing fuzzing, I discovered a bug where the input generated by the fuzzer caused a very long parse times, preventing the program from terminating.

poc.zip

I reproduced this process as follows.

(1) unzip the attached poc.zip

(2) run

cargo afl run url-fuzz-target < ./id:000000,src:002523,time:11346358,execs:197688102,op:havoc,rep:1

Then the program will not terminate as follows.
