That's ZenHub extension flexing out the .repo-nav element, causing elements we add there to flow down.

This is more of a compatibility issue between ZenHub and this extension than a bug from this issue.
Also @fregante WDYT about adding "more dropdown" and "releases tab" inside the ul as opposed to beside it?

Oh, I thought I've disabled all github-related extensions before posting this issue.
I forgot about ZenHub, indeed. Thank you!

Sounds good, GitHub must have changed the DOM.
Also I suggest reporting this to ZenHub. Why are they setting flex on the whole element? Doesn't look necessary.

That did help us find this issue where the elements we add now appear after the settings tab. Sending in a fix for this.

This also explains why I’ve been seeing the Releases being added AFTER the settings tab. That’s not right
