Twenty Sixteen and Twenty Seventeen ignore/override ordered list types

[Greg Raven]

If you set up an ordered list in Twenty Sixteen or Twenty Seventeen, and then try to add a type to it, WordPress ignores the type. You can get only a numbered list.

Can you please explain the steps for reproduction?

Is it like adding an ordered list via content editor and then applying a list-type via CSS?

If yes, please let us know about the following:

1. WordPress version
2. Content editor you are using (Classic or Gutenberg, since the latter is already available)
3. If Gutenberg, please confirm whether the same is happening with the classic editor as well
4. Testing WordPress core and bundled themes recommends that no additional plugins activated except bundled ones like Akismet and Hello Dolly. Please make sure you are testing on a fresh WordPress installation with twentysixteen or twentyseventeen activated.

Thanks!

1) Either apply list styling to existing text, or import an HTML list.

2) Go into the Text view tab in the post editor page.

3) Manually type in a list type, e.g. <ol type="a">

I'm using WordPress 4.9.8 in Classic mode. This is a fresh install, using the Twenty Sixteen theme.
