Attachments in Internet Explorer with hyphen in their file name break the attach functionality on the incident formDescriptionIn IE, when attaching a file containing a hyphen '-' in the filename, no more files can be attached to the same incident and no attachment can be removed. Steps to Reproduce 1. Login an instance using IE11.2. Create a text file to use as attachment.3. Save the file adding an hyphen '-' into its filename (for example: tmp-test.txt).4. Open any existing incident form.5. Attach the file just created.6. Close the Attachments pop-up window.7. Try to delete the attached file or add another attachment to the incident.Notice the buttons to attach or remove a file are not visible on the pop-up attachment wizard.The error message below appears in the javascript console: "XML5645: The specified entity has not been declared. Line: 56, Column 34"WorkaroundAfter carefully considering the severity and frequency of the issue, and the cost and risk of attempting a fix, it has been decided to not address this issue in any current or near future releases. We do not make these decisions lightly, and we apologize for any inconvenience. The only workaround is for the end user to manually modify the filenames before attaching them.
