OK that's weird, thanks for filing.  I really wish we didn't have to take on Bug 1237368 but it dramatically improved both requestAnimationFrame time on the page and scroll time within the console.  If we can find a way to get acceptable perf that doesn't require manual width setting I'd be all for it.  Maybe the work in Bug 1260283 will enable us to get rid of that hack.

It only happens on light Devtools theme; Additional blank space disappears once I resize Console.

OK, it possibly has something to do with scrollbars then (they are floating in the dark theme and don't reserve any space).  Although the blank space appears even when there isn't a scrollbar visible.

Are you planning to fix this in 48?

Thanks for asking.
I'm deferring to Lin's P3 - so, No.

We decided to let this fall off our regression triage radar.

I can't reproduce this anymore. I guess this was an old console frontend bug only.
