Height range modifier does not follow standard UI practice when tabbing to the next field

[julie777]

Describe the bug

When I create a height range modifier for an object I expect tabbing to work in the standard way.
The cursor should be initially placed in the lower end field with the content selected so that I can type the number that I choose. When I tab from the lower field to the upper range field the content of the field should be selected so that I can just type my value.

What actually happens is I select add height range modifier from the context menu for an object and a range is created, with the fields showing the range under layers which has been added under the object. However, those numbers are not the edit fields (as they should be) and the actual height range fields for editing are at the bottom of the window, possibly below many other objects.

1. I have to look to find the editable fields.
2. I have to click to put the cursor in the field because it was not put there as is common.
3. after changing the value for the first field, I tab to the upper field, and the cursor is in the field, but at the end of a default value that was added, so I have to somehow get rid of that value instead of just typing the value that I want. The likelihood of anyone wanting a .5mm range is pretty low, so adding a default value is not very useful.
