Hello,
I tried searching for regression but with no luck, because the issue is reproducing all the way back to 68.0a1(20190502220333) so I think this issue is not a regression and it was introduced as part of Trailhead Desktop First Run feature implementation. Removing the flags accordingly.

This will be solved by the patch for 1561660, which has a couple different fixes for the modal.
