Page Sets; Page Object Height is disabled by default

When adding a new Page Object to a Page Set page using the button on the Page Objects grid, the Type defaults to TextBox for which the height is disabled by default (it is only applicable to multi-line TextBoxes).

If you change the Type to Grid, the Height remains disabled until you check the 'Size to fill empty space on Page' checkbox.

For Grids and certain other Page Objects, Height should not be disabled.
