@Nancy-Salpepi I have not been able to reproduce this (MacBook Pro Intel, macOS 14.5, Chrome 125.0.6422.144). I'm using the URL shown below. When "fuzzing the debug version", were you using any other query parameters?

No I wasn't using any query parameters and that is the link I used. I tried to have it happen again right after I made this issue. I let it fuzz for 20 minutes and nothing.

Sorry I am of no help here.

@Nancy-Salpepi can no longer reproduce. I've tried to reproduce this a few more times, and I've been unsuccessful. And I would expect this to show up in CT with the general fuzz test. So I don't know what to do other than to 🤞🏻 and close this issue. If it comes up again, we'll revisit.
