Programmatic TextField selection doesn't update control

    Details

    • Subcomponent:
    • CPU:
      x86_64
    • OS:
      generic

      Description

      ADDITIONAL SYSTEM INFORMATION :
      Arch Linux with Oracle JDK package https://aur.archlinux.org/packages/jdk/

      A DESCRIPTION OF THE PROBLEM :
      Selecting textfield text using the selection methods such as selectPositionCaret, selectEnd, and selectAll doesn't update the selection shown in the control.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Create sample JavaFX project using provided source code, run it, and type a few characters into the text field after the existing text.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      When a character is typed into textfield after existing text, expect to see anchor move to before first character of TextField and blue selection indicator move over letters "Se".
      ACTUAL -
      As characters are typed into textfield, no selection is shown and the caret stays after the last character typed. The println output shows the caret/anchor and selected text as expected, though:

      caret 2
      anchor 0
      selected text So
