    • Hi Kagami,

      Can you provide a repro or demo for this?

      Appreciate the help,


    • I cannot edit the post, but try typing "delete" in FormData.prototype, "get" in FormData.prototype and so on.

    • (*try typing them on F12 console)

    • Thank you.  That was too easy.  I appreciate you being nice about it.  :-)

      I was able to repro this in 15063.608 and in a more recent development build.

      Appreciate the help,
