1262298 - FileReader cannot reload data from File objects

Status: RESOLVED DUPLICATE of bug 1260606

(Firefox :: Untriaged, defect)

Description

[tgvaughan]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160315153207

Steps to reproduce:

Prior to 45, I could use the following to reload a file for which I'd previously obtained a File object:

var reader = new FileReader();
reader.onload = fileLoaded;
reader.readAsText(fileObject);

where fileLoaded is the onload event handler.


Actual results:

After FF v45, the onload event handler is only called the first time I try to read the file.  Subsequent calls (to retrieve updated file contents) do not call the event handler.


Expected results:

The onload event handler should have been called.
