I’m on a 1080P display with 125% scaling in windows. The width of the screen (in the browser) is 1433.6, and I’m using Edge
Thanks for reporting this. We’ll look and see if we can figure out why this might be happening. 
Following up here to report that we have an update that should go out in our next platform update to resolve this issue. Likely not next week due to the US holiday, but the week after.
