Wt

With github Wt 3.3.6-6-gbadb151, visiting the widgetgallery navigation/tab-widget by initial URL causes a couple of problems with the bootstrap2 and bootstrap3 themes:

1. The closeable tab does not close when the "x" is clicked.
2. The tabs are rendered with extra space below them in Firefox 47. Chrome 53 and IE 11 both display extra space below the tabs as a visual glitch, then render the page correctly.

If another page in the Widgetgallery is displayed first, the closeable tab renders and works correctly.

The issue is currently observable at: https://www.webtoolkit.eu/widgets/navigation/tab-widget

This seems to be related to progressive boot and a workaround is to configure navigation/tab-widget to use the default bootstrap method in the widgetgallery wt_config.xml.
