With the addition of the Public Access tab, the form tabs start wrapping when the viewport width is around 1000px. (In Spanish, they start wrapping at around 1100px.) For example:

I don't think we're planning on a broader change right now around how the form tabs wrap. However, it would be good to adjust the appearance of the draft box: there shouldn't be a space between the draft box and the content below.

The screenshot above shows the draft box when it contains tabs. This is what it looks like when it contains the create button:

We could try sizing the draft box so that its height matches the form tabs. That way the form tabs and the draft tabs would continue to be in line:

We could also bottom-align the draft box:

I think this will mostly be solved by #785 (maybe not fully for Spanish). We're probably going to rework the draft experience at some point, which might help as well.
