I reached out to :jdescottes in the DevTools matrix channel, and said given my changeset, it's very likely that you are slightly changing the markup / events / style the browser toolbox needs to display when starting the browser toolbox inspector. Their guess is that it's a bit slower to open because it needs to display more data, but that's not really something we should worry about. It's unlikely I actually regressed the performance of the Browser Toolbox.
WONTFIXing this given the above.
