I was adding some new fields in the res.config.settings model, and I ran into an interesting visual inconsistency. I have 2 modules adding char fields to this screen, and I copied and pasted both the xml and the python code for them, and just changed the names. The result was that one group of fields were really long (from one end of the page to the other) and the other group was really short (less than half of the page)

Here's the code involved:

## EDIT: Turns out when you paste xml/html it tries to render it, so here's a pastebin instead: pastebin

My question is: What might be causing this difference, and how can I manage it?
