GUI: GRAPHICS: Selection highlighter broken in Save dialog.

[macca8]

After opening a Save dialog in list view, the first time any empty slot, or saved game that isn’t write protected, is selected, a green highlight bar is displayed, with the flashing text-insert cursor (and its white mask(?)) overlaying the bar (see attached screenshot).

If another slot (empty or occupied) is then selected without having saved, the new slot now displays the flashing text-insert cursor correctly (if not write protected), but without the expected green highlight bar (see attached screenshot).

The issue appears to be initiated by the presence of the text-insert cursor’s mask when the cursor is first displayed in the dialog, and affects all subsequent switches (whether or not the cursor is displayed).

I’m testing 2.8.0git3759-g6c45026b (Apr 11 2023) on macOS 10.11.6, but this bug dates back to before 4 March 2023 (restricted to 2.8.0git daily builds).

To reproduce:

• Open any game’s Save dialog.
• If necessary, switch the dialog to list view.
• Select any slot or saved game that’s NOT write protected.
• Without clicking Save, select another slot.

If necessary, you can test either the 2.7.0 release or any recent 2.7.1pre stable build to identify the expected behaviour.
