Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Run a workflow
2. When the dialog pops open to enter a parameter, hit escape
3. It keeps on going to the next parameter and eventually the job is run

Expected behavior
Hitting escape should terminate the running of the workflow while entering parameters as per the prompt in the popup

Screenshots

Extension Version
0.27.2

Additional context
Another issue found:
When the prompt is shown, if the IDE loses focus due to a global mac keyboard shortcut (I was popping open a clipboard tool to paste in a value into one of the parameters), it skips that step (not sure if it entered a value or just treated it as if I hit enter). The keystroke I used BTW was Shift+Cmd+C
