Re: [csswg-drafts] [css-logical] Add `block-start` and `block-end` to `caption-side` (#9623)

If they don't bring any new functionality, I'm not convinced this is worth it.

That said, it's maybe a bit strange for `top` and `bottom` to be [flow-relative](https://drafts.csswg.org/css-writing-modes-4/#logical-directions), while `left` and `right` are [line-relative](https://drafts.csswg.org/css-writing-modes-4/#line-directions):

| Keyword | Type | Meaning |
| - | - | - |
| `top`, `bottom` | flow-relative | block-start, block-end |
| `left`, `right` | line-relative | line-left, line-right |
| `inline-start`, `inline-end` | flow-relative | inline-start, inline-end |

If compat allows it, it could make more sense to treat `top` and `bottom` as line-over and line-under, and then add `block-start` and `block-end` as flow-relative:

| Keyword | Type | Meaning |
| - | - | - |
| `top`, `bottom` | line-relative | line-over, line-under |
| `left`, `right` | line-relative | line-left, line-right |
| `inline-start`, `inline-end` | flow-relative | inline-start, inline-end |
| `block-start`, `block-end` | flow-relative | block-start, block-end |
