--- Comment #43 from Minsheng Liu <lambda at liu.ms> ---
Thanks Darin for commenting! I am completely new to WebKit. I really hope there is some detailed documentation on layout stuff. The only thing I could find is the 2007 blog article (https://webkit.org/blog/116/webcore-rendering-iii-layout-basics/) but the series feels more like a tutorial on how to write a simple browser…

In any case, if some layout expert could take a look at it, I have a question. Since the stretch width of a stretch operator depends on the width of other elements in a fairly complicated way, I am unsure how the code behaves when a stretch-width-affecting element is changed (e.g. by JavaScript). In WebKit, which part of code determines which elements become dirty after DOM change? I have not yet tested the issue as there are other layouting/painting problems regarding DOM change, page size scaling, and scrolling, but I think we should be cautious here.
