Prompts not properly masked

### Expected Behavior

"Password" prompts (those defined with the "Mask Text" checked) should not echo actual characters, but rather hide them (*****).

This has been broken for a while (6 months maybe?).

### Actual Behavior

I can see the password I enter.

### Reproduction Steps

The prompt is defined in the **Body** area...

... as a **_Prompt**...

... but when I **Send** the request I can see what I type

Reproduce the issue using a masked Password prompt in the request Body area and confirm that entered characters are visible after sending. Trace the prompt handling from the Body prompt configuration to the send flow; done means masked prompts display hidden characters rather than the actual password.
