Implement size property for more form elements

We sometimes use display forms in a landscape layout, rather than the default vertical ‘left-of-the-map’ position. At other times, we temporarily hide the map altogether to focus on a display form. Both situations result in ridiculously wide input boxes. The current workaround is to pad the form element with empty Text elements, but it's, well, a workaround.

Since v 5.39, the Number form element has a size property that lets us reduce the width of the input box, which is very welcome. I think that many other form elements would benefit from this same property, i.e. Text Box, Autocomplete, Dropdown, Date Picker, etc. Could this please be added?
