Steps to reproduce:

i implemeted a onPaste event handler and used the following code.

  validatePasteItems = (clipBoardData, uploadCallback) => {
    const { setAlert } = this.props
    const { value } = this.state
    const { items: pastedItems = [] } = clipBoardData
    const totalItemsPasted = pastedItems.length
    for (let i = 0; i < totalItemsPasted; i++) {
      const pasteItem = pastedItems[i]
      const { type: pastedFileType = "" } = pasteItem
      if (pastedFileType && pastedFileType.indexOf("image") !== -1) {
        let pastedFileBlob = pasteItem.getAsFile()// returns null if i paste a pdf file. in chrome it is working.
        if (pastedFileBlob) {
          //this is not executed.
       }
}
}
}


Now copy a pdf file to clipboard, and paste into a text/textarea field.



Actual results:

the issue is, it is working in chrome , it is not working in firefox.


Expected results:

It should work consistently in browsers.
