Tooltip doesnt change if Font is changed to Dark High Contrast on Windows

Run the attached program and hover the mouse to see the tooltip window.
Change the windows theme to Dark High Contrast Theme.
See the tooltip again.

The colour of the tooltext and background has changed, but this doesn’t match with the native windows one. ( If tested with any windows app in parallel )

Attached is a patch too which fixes the problem, needs to be verified.
Also a couple of more questions from the customer,

1) Why is there hard coding white for the disabled case.
2) Are all the other roles needed for Windows styles?
