@dmitrii-drobotov @LeafShi1 can your teams take a look and see if we can set the selection color in our code, or if this is solely done by windows in the Common Controls ListView control. I'm thinking it's most likely the ListView and we can't change it so we'd need an exception.

@merriemcgaw , we asked Dmitrii about this, and find that there is no method we can use for that and it's on the Windows control side.

Thanks @SimonZhao888 I think our existing exception around Common Controls should cover this case. I will review with the accessibility team.
