Re: [csswg-drafts] [css-overflow-4] max-lines and independent formatting contexts (#12962)

+1 to what @bfgeek said.

The use case would be a listbox select, this comes up from https://github.com/w3c/csswg-drafts/issues/12510.

Consider:

```
<select-like-thing>
  <complex-option>....</complex-option>
  <complex-option>....</complex-option>
  <complex-option>....</complex-option>
  ...
```

You want to clamp at 2 items, but you don't want to recurse into the options, nor skip counting the options. So if options are their own BFC (`display: flow-root` or so) it allows to achieve the use case trivially (`select-like-thing { max-lines: 2 }`).
