Created attachment 470050 [details] File to reproduce the issue During development, I have encountered a specific bug in Safari. Specifically, after initiating a file download using a dynamic <a> element, subsequent HTTP requests made with the fetch function fail with a `TypeError: Load failed` error. This issue only occurs after the download has been initiated and does not affect any fetch requests made prior to it. The steps to reproduce are as follows: 1. Open the Developer Tools' Console tab. 2. Click the "Start Download and Fetch" button to start the file download and initiate fetch requests to `https://webkit.org`. 3. Observe in the console that fetch requests made before the download succeed, while fetch requests made after the download fail with a `TypeError: Load failed` error. This issue could have a significant impact on web applications that need to perform data communication with servers after downloading files. I have attached code that can reproduce this issue, and I kindly request an investigation for a possible fix. Thank you for your attention to this matter.
