Chrome Version 75.0.3770.90 (Official Build) (64-bit)
Mac
All versions 1.6.7 and later. Looking at the diff between those versions didn't give me too much insight, but I am not particularly familiar with the source.


Open the most recent version in the most recent version of Chrome on Mac.
This happens on any Chromium based browser, had the same issue in Brave.
Bopping into dev tools, I was able to fix it by giving the element that had class .cRrmDs a min-height: 0.

should we just remove this line?
I believe that will at least fix this issue fine, but there are still other height/scrolling issues with the tracing div. I ended up using version 1.7.10 which didn't have most of these issues.
