Steps to replicate the issue (include links if applicable):
What happens?:
In the Composition, the Condition and the Then have both Argument references. The Key Ids on those are just a bit too tight when they hug the value.
What should have happened instead?:
The fields for the key id should be wide enough to display the whole Id.
