While following the development of the Ladybird browser[0] I found out many of the Web Platform Tests[1] are related to CJK rendering which I found surprising, but seeing this it makes a lot more sense.

Another problem for years in Chrome is, if a line is wrapped between two Chinese words, Chrome will insert a space between them in rendering. (Firefox doesn't)

In short: don't use "float: left/right" for anything besides real floating images.

In this case a "display: flex" on the <a> element would be a much better solution.

Not surprising.

The homepage of Google has n-e-v-e-r had an error free console, which I find funny considering it's literally a white page with a logo and a lonely text field, and considering that Google expends so much effort trying to sling their design methodology onto everyone. "Do as I say, not as I do."

> However, CJK languages don’t rely on spaces as word separators, which allows line breaks to occur between any characters.

No, not for Korean. We do have spacing rules like European languages. And we don't like a situation when an arbitrary line break is added in the middle of the word.
