Details

nsDocumentEncoder calls nsIOutputStream::Write in various places and then ignores the out parameter indicating how many bytes were written. nsIOutputStream.idl is relatively unambiguous about this: > * @return number of bytes written (may be less than aCount) This bug seems to have been introduced in the patch for bug 50742 and remained unnoticed for nearly 15 years, until I tripped over it while working on bug 1101100.

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority.
