Desktop Content Explorer: Content Browser not working for Inline Links and Active Assembly Table editor for slots

[natechadwick]

Describe the bug

The Content Browser just hangs with a loading screen when inserting Inline Links, Inline Images, Inline Templates in the Rich Text editor or when trying to add content to a slot using the Active Assembly Table Editor. This behavior was introduced in recent Java Updates and appears to be caused by the removal of support for synchronous JavaScript calls from the JavaFX WebView that is used when running in Desktop Content Explorer mode. If run as an applet, or if the Content Browser dialog is opened in a regular browser window (Edge, Chrome, etc) the dialog works as expected.

To Reproduce

Steps to reproduce the behavior:

1. Run Desktop Content Explorer
2. Edit a Content Item that contains a Rich Text field. Like a Generic item.
3. Try to use the Insert Inline <Link, Image, Template> menu item or buttons.
4. The dialog will open but not load as expected.
