The JavaFX API version number is added to the right side of the header of each page in the javadoc-generated API docs using the `-header` option. The version number is not vertically centered in the header banner, but is top aligned, which looks out of place relative to the other elements in that banner.

Compare the "JavaFX 23" to the "Java SE 23 & JDK 23" on the following two pages:

https://download.java.net/java/GA/javafx23/343fae14109c42b09c0437fc90a10d4b/docs/api/index.html
https://docs.oracle.com/en/java/javase/23/docs/api/

This was noticed while fixing JDK-8340829.
