Form URL Encoded requests do not expand variables to their value

[kzndzhiro]

Thank you team for developing this nice looking tool.

I was exploring by importing a collection and noticed an odd behaviour with respect to Form URL encoed request.
When in the body I have a param with a variable value it seems that the variable is not expanded prior to sending the request:

The message on our systems led me to belive that this is the issue:

"message": "invalid_grant: Invalid refresh token: xxxx..._ui}}",
