What do you expect it to do differently in that case?
There are lots of different options: https://en.wikipedia.org/wiki/Widows_and_orphans#Guidelines
The kindle also doesn't support proper kerning. Sorry if I told you that and you can't unsee it now.
But you can install 3rd party reading software on jailbroken kindles like koreader that fixes some of the deficiencies.
Although Koreader has been originally developed for e-ink devices. I'm not sure how well it has been optimized for normal tablet screens.
