@krzysdz commented on GitHub (Sep 7, 2020):

It appeared in commit 5330759 (PR #7447) because of a bug in MUX (microsoft/microsoft-ui-xaml#3104). There's already a PR for MUX, which should fix it (microsoft/microsoft-ui-xaml#3118), but it needs to be merged and included in a new (pre)release, before it can be updated in terminal.
