bug: Swipeable Segments

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v8.x

Current Behavior

Swipeble segments' segment buttons not working with variables:

<ion-segment mode="md" [value]="value">
  @for (button of buttons; track button.label) {
    <ion-segment-button [value]="button.value" [contentId]="button.value">
      <ion-label>{{ button.label }}</ion-label>
    </ion-segment-button>
  }
</ion-segment>

If I add manually segment-button with the content-id of the first segment view (general) it works:

<ion-segment mode="md" [value]="value" (ionChange)="onChange.emit($event)" [scrollable]="true">
  <ion-segment-button [value]="" content-id="general" style="margin-right:0px"></ion-segment-button>
  @for (button of buttons; track button.label) {
  ....

If I add the same like this [contentId]= it doesnt work:

<ion-segment mode="md" [value]="value" (ionChange)="onChange.emit($event)" [scrollable]="true">
<ion-segment-button [value]="" [contentId]="'general'" style="margin-right:0px"></ion-segment-button>
@for (button of buttons; track button.label) {

Note: ion-segment-views are swipeable, swiping doesnt change active status of segment buttons or clicking segment-buttons doesnt change the view.

Expected Behavior

Swipeable tabs would work when using variables for content-id / [contentId]

Steps to Reproduce

Play around with the code on "current behaviour"
