Description:
When pasting an image into a sheet, text color with highlight color in textbox is not reversed

Steps to Reproduce:
1. Open new Calc. ( with light theme )
2. Create Textbox, and insert Text "Red".
3. Apply highlight-color red to the text.
4. Text color changes to White.
   This effect is the same as setting the cell's background color to red.
   In previous versions, it would remain black.
5. Copy the "range" containing the text box and paste it onto the sheet as an image (e.g. GDI).
   ( by dropdown-menu of paste-icon )

Actual Results:
6. The text color becomes black.

Expected Results:
6. The text color remains white, just like in the display.


Reproducible: Always


User Profile Reset: No

Additional Info:

Note that in Version 26.2, the text color doesn't invert during step [4].

Version 26.8 appears to have implemented the correct fix, but this still seems to be only partially complete.

In the next version, the on-screen text color won't invert like in older versions.
If pasted as an image, it will display identically to the screen.
From this perspective regarding image display consistency, it's accurate.
