Fun fact: In perspective of file size, in Chrome's final bundle, a large chunk of bytes were the libicu, and 80% of libicu are chinese characters. So everyone must download extra megabytes of software for modern CJK word segmentation

Nice writeup. But it doesn't explain how a paragraph of N words is redrawn in O(1) time if one adds one word to the beginning.

For the record, I much rather that old JB browser than Chrome. It's still around if you want to install it but "inverted rendering" doesn't work on newer android versions.
