Fix rect bottom right edges

Close#368.

Thanks for the PR, I think this make a lot of sense to me!

But again, IMO it's not a really a solution but a mitigation - And I am looking forward we can reach the point that we define a sound and uniformed backend abstraction at some point.

The change itself looks good to me!

I am wondering if @facorread and @AaronErhardt have any comment on the PR.

[facorread]

I agree! I know it can be frustrating that a project chooses a long-term abstraction over a short-term solution, but the discussion here highlights the need for it. Let us try to build it!

Looks good to me

This is nitpick of course, can you please address the warning below? It looks like removing one line should do it. Thanks!

[shinmili]

@facorread Thanks for pointing out. The warning indicates the test below is actually not run on GitHub Actions, so I edited the test command line to make it run, instead of removing the line with warning.
