Selection box in LibreOffice Calc is invisible when using light theme

[Romchec]

What Happened?

It's hard to use LibreOffice Calc because selection box is blends into the background.

Steps to Reproduce

1. Set one of default elementary OS themes
2. Turn on light mode
3. Open LibreOffice Calc
4. Select cell with cursor

Expected Behavior

Selection box and dot at the bottom right corner should be more visible, not white. Here's how it works in dark mode and another GTK theme:

OS Version

6.x (Odin)

Software Version

Latest release (I have run all updates)

Appending the style sheet with this (for Blue, in this case) worked around the issue for me.

* {
  -gtk-secondary-caret-color: @selected_bg_color;
}

.view:selected:focus, .view:selected, iconview:selected,
.view text:selected,
iconview text:selected,
textview text:selected {
  background-color: @selected_bg_color;
} 

Result:

LibreOffice seems to pay attention to these for setting the selection colours. It perhaps is a clue as to how to fix the problem permanently going forward?
