Description Celeste Glavin 2023-10-24 13:12:24 PDT
Steps to reproduce:
- define an anchor element with the download attribute and a url to download either a TXT or XMl file
- fire the click event on iOS Safari (Current version is 16.6.1)

Expected:
- Download starts

Actual:
- file is opened in the current tab

Example of code:
const downloadExportUrl = (url) => {
  const a = document.createElement('a');
  a.href = url;
  a.download = '';
  a.click();
};

Same issue when trying to download a pdf file in the form of Blob:

    const pdfBlob = await pdfBinaryRes.blob()

    const blobUrl = window.URL.createObjectURL(pdfBlob)

    const link = document.createElement('a')
    link.href = blobUrl
    link.download = filename
    link.click()
