update chrome kernel?

[rarnu]

hi @ks32 , would you please update the chrome kernel version to 81 or higher? Now the version 77 has some render errors just like drawing ruby-rt in Japanese.

hi @ks32. Thanks for your excellent work! If you don't have time to update chrome kernel, maybe you would consider to provider step-by-step documentation so we can do it ourself. It would be a great help for us.
