Like, a colleague was working on code that would reach into the DOM and just tweak the CSS for a bunch of items, delete other items, move things around, and maybe 40% of the time it would work as intended, and 60% of the time, boom, dead browser, segmentation fault.
React, where it's just normal for Javascript to rewrite the entire page in response to a keystroke, would have been completely unthinkable, there's no chance you could fill out an entire form before the browser crashed if you do that.
We are talking about V8 being released in 2008, Chackra in 2011, and SpiderMonkey in 2009.
With GCs that can handle the amount of stuff that React throws away on each update.

Phoenix saved us.
From a community perspective, it would have been a great thing to push it forward further, spend resources on it, and have at least one web browser that isn't somewhat wicked.
Admittedly, back then, we all hoped that Firefox would be that 'friendly' browser, and it probably truly was at that time.
Time has changed. Now I'm forced to like a browser that is always just slightly less evil than a one that would even IE look friendly. And with every version we are now waiting when they also will drop the manifest v2 support for dubious reasons. And even if that will never happen, they will continue to find other ways to disappoint me.
Yes, khtml was at least a nice time to remember. :)
PS: My personal feeling is that "impressive but not good enough as a daily driver" was and is true for some more KDE apps. This is why I use Plasma Desktop, but barely any more of their apps than Dolphin and maybe kate to some degree. I know all you're going to say now about free software and how it works and so on, and you're right, but technically, it would be sooo much better if just half of the email client projects (or office suites, IDEs, photo editing, ...; you name it) would exist, but with more developer powers behind it. But I'm digressing......
Shame it hasn't kept up.
