With the the dark mode active the conditional formatting using the colour scale option will create a hard white font regardless of colour background.

2. Create a list of data in a column (ie 1-20)
3. Select this data
4. Press the conditional format icon on the toolbar
5. Choose Colour Scale
6. Press OK (to accept default settings)
7. Done

Actual Results:
A list with the numbers 1-20 in white text with cell background colours ranging from red through yellow to green.

Expected Results:
Similar to above, however there should be black text on light colours (ie yellow) or as needed.

User Profile Reset: No

Additional Info:
This behaviour differs from a cell manually formatted with those background colours and using the automatic font colour.
