---------------------------------------------------

More a question than a bug right now.. is the intention for hidden params to affect the UI? See screenshots below.

Before (no params at all):

After (added single hidden param):

Then:

As you can see, adding a hidden param affects the UI experience for the Input step, requiring an extra click through. Not the end of the world but... is this expected? A limitation of sorts? Is there a workaround available?

Thanks,
Michael

### Expected Results

Expected the Input UI to display as if there were no params at all.

### Actual Results

Input UI is changed, requiring users to click through before finding the familiar 'Approve/Decline' options.

### Are you interested in contributing a fix?

Yes. Relatively new to Jenkins plugins though, would appreciate any pointers.
