Since the refactoring of the JS relational model (d4fe919d),
the list is not fully re-rendered after field updates,
such that a fixed narrow column width is added at first rendering
if there are no triggers shown on any row, and cannot be updated.
We need to override it by providing a `width`, which was already
a supported attribute but not declared in rng.
