1020990 - FileReader does not fire progress event at 100%

Status: UNCONFIRMED

(Core :: DOM: Core & HTML, defect, P5)

Description

[M8R-p7]

Firefox only emits Progress events until the file has been loaded, while Chromium and Internet Explorer emit Progress events up to and including 100%.

The W3C FileAPI spec specifies that a progress event must be fired "at 100% completion of the read operation" ( http://www.w3.org/TR/FileAPI/#events )

Attachment: Testcase: Final reported loaded bytes

Not sure if a testcase is required, but have this anyway to clarify: this outputs the Loaded Bytes count of the last Progress Event received before the Load Event.

In Firefox, the result will be either 100% or less, depending on whether the whole file could be loaded at once.

I haven't yet received less than 100% in other browsers (expected behavior).
