Bug 436320

SUMMARY
In konsole version 21.04.0, when highlight text with mouse left-button, the font color remains the same, and highlighted background is dark grey.

If you change the color scheme to 'Black on White' and print some text in cyan [code]echo -e '\e[36;1mtext\e[m'[/code] (or yellow, 33 instead 36), there is no difference between non-highlighted and highlighted text. 

STEPS TO REPRODUCE
1. Select a text with mouse in konsole.
2. The font color remains the same and background is dark grey (or transparent if the background color is white).

OBSERVED RESULT
It is very difficult to see what is highlighted.

EXPECTED RESULT
Would be better if highlighted text be the same as the previous konsole version 20.12.3, in reverse colors, e.g. white text highlighted becomes background color text with white background,
green text becomes background color text with green background, and so on.
