Dear Maintainer,

   * What led up to the situation?
        Installed Debian 13. Enabled High Contrast in GNOME Accessibility settings, because I am partially sighted.

   * What exactly did you do (or not do) that was effective (or ineffective)?
        I can find no way to make selected text visible while High Contrast is on. The tool bars are so difficult to see they are almost unusable. I have tried different settings and themes from the LibreOffice options and this has helped with the visibility of the toolbar but there seems to be no way to make selected text visible from within LIbreOffice. If I turn off GNOME Accessibility High Contrast, LibreOffice switches from "light" mode to the system default "dark" mode. Selected text becomes visible and the toolbars much easier to see. I need high contrast for other apps and the system GUI, so my only know option at the moment is to change the Accessibility setting every time I what to open LibreOffice.

   * What outcome did you expect instead?
        Knowing that some very good work has been done on Debian accessibility (thank you!) I was expecting LibreOffice to be as good or better than in was in Debian 12.
