There are some issues generating JavaFX docs.

The Property Summary has visual issues and JavaScript issues.
The summary table should probably not have "method" tabs, it should probably have a single "Properties" tab, by analogy with "Fields".

The method tabs in a Properties Summary table cause excess JavaScript to be generated which messes with the method tabs in a Method Summary table. (Clicking the method tabs causes visual changes in the Properties Summary table.) See attachment for example of excess JavaScript.

The Field Summary table looks wrong in this file:

Also in the second screenshot, notice the excess whitespace above the table tabs for the Property Summary Table.

Also in the second screenshot, notice the different text alignment for the description in the Property Summary Table.
