[csswg-drafts] [view-transitions] How do the writing-mode and direction properties affect the view-transition pseudo-elements? (#8230)

bert-github has just created a new issue for https://github.com/w3c/csswg-drafts:

== [view-transitions] How do the writing-mode and direction properties affect the view-transition pseudo-elements? ==
After reviewing the spec for i18n issues, I wasn't clear what the function of the 'writing-mode' and 'direction' properties was. They occur, e.g., in 8.3. [Setup view transition](https://www.w3.org/TR/2022/WD-css-view-transitions-1-20221124/#setup-view-transition):

>    Set capture’s [old styles](https://www.w3.org/TR/2022/WD-css-view-transitions-1-20221124/#captured-element-old-styles) to the following:
>    [...]
>
> *   [writing-mode](https://www.w3.org/TR/css-writing-modes-4/#propdef-writing-mode)
>    The [writing-mode](https://www.w3.org/TR/css-writing-modes-4/#propdef-writing-mode) of element.
>  *  [direction](https://www.w3.org/TR/css-writing-modes-3/#propdef-direction)
>    The [direction](https://www.w3.org/TR/css-writing-modes-3/#propdef-direction) of element.

And similar in 8.9. [Update pseudo-element styles](https://www.w3.org/TR/2022/WD-css-view-transitions-1-20221124/#update-pseudo-element-styles).

These properties are set on elements that are images. But they don't have effect on images, do they? In other words, would anything change if these properties were omitted from the style for these view-transition pseudo-elements?

If they do have an effect, a note or an example could be useful.

And, please, write the answer to this issue, and any explanation in the spec, in simple language! We (the I18N WG) found the spec rather difficult to understand…
