Pressing enter with the cursor in the github repository led to spawning not image building

[consideRatio]

I had my cursor active in the text field of the github repostiroy input, and then I pressed enter. It led me to directly spawn using some other image, and now what I expected - that I'd trigger a build.

I'm not sure whats possible do here UX wise, but it would be better to not launch or build over than launch if it doesn't make sense to trigger a build or if that isn't possible.
