Scroll Bar Contrast Ratio for border is less than 3:1

The Scroll Bar in 5.15.6 has a contrast ratio that is less than 3:1. A user with low vision might get affected as user won't be able to verify selected controls, which may impact the efficiency of the user.

To Reproduce: Create a Qt window and add a scroll bar (horizontal or vertical) and open accessibility insights. While in Insights select the Contrast screen (3rd button on the left side, looks like a paint tray) and select the scroll bar and then select the border of the scroll bar. Observer that the ratio is not 3:1
For Reference look at the photo(s) attached.

During research on this I found that scroll bar borders and colors can be changed via CSS, but doing so for this situation would cause another Accessibility Bug when High Contrast mode gets disabled and the item does not follow the rules for high contrast mode.
