Parameter window does not have the right width when replaceable packages are included

[Francesco Casella]

Please check the attached test case. When you double-click on the teeJunctionIdeal component, a Parameters window pops up with a field for the replaceable Medium model.

If you click on the drop-down menu, some of the class names are shortened in the middle, with ... showing up instead of the missing text. In fact, in order to see those names complete one has to manually increase the width of the parameter windows, so that the entire fully qualified path can be seen.

I see that the width of the Parameter dialog editor is not constant in general, and is probably adapted to get all values to fit in drop-down menus. Unfortunately, this adaptation is not correct in this case, because it causes some names to be unnecessarily clipped in the middle.

@adeas31, is this difficult or easy to fix?
