Feedback Understanding Label spacing

I've been working with UI Toolkit for quite a bit and I must say I'm pretty satisfied with it! However, there's a couple of things that bug me a bit and it's the lack of consistency of the "growth" rate of an in-line Label and the control next to it.

If someone at Unity could shed some light into this would be greatly appreciated!

Let me put some examples of what I'm referring to.

The Samples window that UIToolkit comes with have a fixed Label width of 117px + 3px of padding. The control on the right is what grows/shrinks:



However, when creating a UIToolkit custom editor that uses PropertyFields, the behavior of the Label is that it grows with the control more or less at the same ratio, keeping the proportion (just like IMGUI controls):



However! When using a TextArea, the behavior of this control is back to the first example, where the Label occupies a fixed value of 120 pixels and the rest is filled by the control:



Could you tell us what's the real expected behavior? Is this something that's still under WIP or did you settle in a specific value? It grinds my OCD gears seeing all controls misaligned

EDIT: Just to summarize, when creating a control using TextField, the label width is different than when using PropertyField, and binding it with a string SerializedProperty.

 

I've reported it as a bug (case 1407494), since looks like it should definitely not behave like that.
