File Attachment information is getting carried over on subsequent issue creates.

If the user creates an issue with an attachment and then attempts to create a subsequent issue (without an attachment), they get an error stating, "Temporary attachment not found. Session may have timed out before submitting the form".

It looks like the file attachment data is getting carried forward from the previous issue. It appears this only occurs if the user opens the Create Issue form by right clicking on the "Create Issue" button and choosing the option to open it in a different browser tab (See Step to Repeat below).

Steps to Repeat:

1. Create the first issue (with an attachment):
   • Right click on the "Create issue" button and choose the option to open it in a different browser tab.
   • Fill out the necessary fields on the new tab, attach a file, and submit the issue.
2. Attempt to create the second issue (without an attachment):
   • Again, right click on the "Create issue" button and choose the option to open it in a different browser tab.
   • Go to the new tab and view the Attachment area. Notice the file attached to the previous issue is listed (For the purpose of this test, don't uncheck it).
   • Fill out the necessary fields and submit the issue.
     RESULT: The following error is thrown: "Temporary attachment not found. Session may have timed out before submitting the form"
