Fix unreadable code blocks chrome.css

[pickfire]

I am not sure cases .hljs is used so I can't specifically enable this so I added a few other whitelisted stuff.

Before

After

Screenshots taken from helix editor. https://github.com/helix-editor/helix although the styles are a bit custom but these parts are not customized.

Thanks for the PR! Can you provide some background here? What does the original markdown look like? Why is it being rendered in such a strange way? Why add td and p to this rule?

I wouldn't expect this change to be needed. Inline code is intended to be highlighted except for exceptionally rare circumstances (like a tags).

The blockquote parts seemed to have the same background and foreground.

## Normal mode                                                                  

### Movement

| `k`, `Up`    | Move up                                            | `move_line_up`              |

Not sure why is it being rendered in such as strange way. So I had to add td and p to those .hljs that was being generated here to fix the issue.

I don't see that when built locally:

It looks like they have a custom theme. Perhaps there is an issue in their theme? Maybe it is using an out-of-date copy?

I updated the copy using the new css, maybe will try again, only some parts are different from what I see which likely won't affect it. I almost compared it one by one.

It is unlikely the CSS, but the fonts. mdbook no longer loads fonts from google's CDN, and uses a particular version of source code pro to avoid a problem with firefox on macos (#1307).

Oh weird, I tried doing a new mdbook and can't seemed to reproduce this, probably something funny we did with our css.
