Re: [csswg-drafts] [css-overflow] Bidi handling for text-overflow and line-clamp ellipses (#12617)

As I was making the spec edit for this, it was not clear to me whether the resolution saying "take their bidi direction from the paragraph" matched the previous conversation. Per the log:

> <TabAtkins> fantasai: making sure I understand. So it is isolated. as an isolate it behaves as a neutral char at the paragraph's embedding level. within the isolate it takes the direction of the paragraph...
> <TabAtkins> florian: are you distinguishing between para or block container, or just saying para because it's easier?
> <TabAtkins> fantasai: para is the bidi term. block container is what I mean

Let's say we have a block container with `direction: ltr; unicode-bidi: plaintext`, but UAX#9 P2 and P3 sets its base directionality to RTL. The resolution language could imply that the ellipsis inline acts as if it had `unicode-bidi: isolate; direction: rtl`. Should it be `direction: ltr` instead?

This gets somewhat tricky when you have multiple bidi paragraphs in the same block container, because with `unicode-bidi: plaintext`, the different paragraphs could have different base directionalities.
