Steps to reproduce: 1) Have a PowerApp with 21 data sources 2) In the editor, click View, click Data sources.
3) A box should show up with a list of Data sources.
Expectation: I should be able to scroll through the entire list of 21 Data Sources
9 are visible. I can scroll, but only down to the next-to-last item. Scrollbar appears to be cut off by the bottom of the page, as well. It's as if the box extends just a little too far down. If I zoom the page out far enough I can expose the missing item. Although the experience is different, this feels like it may be similar to the issue impacting the list of flows.
