In the following code, the first console.log message prints pretty much instantly. Then everything just hangs (I'm initially assumed it was waiting for the body of the response to be returned). The Body of the response is only about 26K, the time waiting seems to be indefinite UNLESS, I shake the phone and interact with the debug menu. As soon as I interact with the debug menu, the promise resolves and everything moves along as expected. My interactions with the debug menu can be simple, like hide inspector, show inspector, just takes something to kick the promise resolution into gear and everything is fine.

```
fetch(SEARCH_URL, requestBody)
    .then((response) => {console.log(response); return response.json();})
    .then((responseData) => {
        debugger
        ...

```

Note:
Disconnecting from the debugger and running the code does not exhibit the slowness (and not being connected to the debugger ignores the debugger statements)

And yes, I have rebooted the computer.
