I'm a bot! I can only do what humans tell me to, so if this was not helpful or you have suggestions for improvements, please ping or otherwise contact @TimNN. (Feature Requests)

@JohnTitor Thanks!

First time contributor here and the UI tests are difficult to get used to, I'm unable to build Rustc so I cant test changes locally, so far its been hit and miss :(

[JohnTitor]

Uhm, applying suggestions on GitHub ignores blank lines, so could you insert them on your local and push it? Anyway, thanks for considering the contributions.

[JohnTitor]

Also, it's good to squash commits into one.
