Thanks for the issue. I can reproduce this behavior. This line looks to be the culprit: https://github.com/ionic-team/ionic-framework/blob/main/core/src/components/segment/segment.tsx#L310.

We determine RTL by looking at the document direction, but we do not look at the dir set on the host element. In other words, running your entire app in RTL mode is fine, but specifically running ion-segment in RTL mode does not work.
