Custom Fonts in User Agent Stylesheets

This seems like a bug. Certainly overriding Region#getUserAgentStylesheet() is the preferred way of customizing styles for a control.  Maybe the styles from the Region UA stylesheet aren’t being considered when doing a font lookup. That would for sure be a bug.

But there are a lot of moving parts.

Are there other stylesheets that might take precedence? Are there other styles in the custom stylesheet that are/are not working? Do you have a short example that reproduces the issue?

Subject: Custom Fonts in User Agent Stylesheets

I noticed today that the custom fonts I defined in a user agent stylesheet of a custom control are not being used. It only started working when I “manually” added the stylesheet to the control via getStylesheets().add() instead of overriding getUserAgentStylesheet().

Does anyone know if this is intentional or a bug? Are there certain things that JavaFX does not support depending on the “type” of stylesheet?
