### Ionic Framework Version

v8.x

### Current Behavior

v8.8.1 regression from v8.7.17.

IonLabel with dynamic text node child corrupts global styles.

Workaround: `{myString}`

### Expected Behavior

No change to global styles when rendering string in IonLabel

### Steps to Reproduce

1. Render IonLabel
1.1. Pass a dynamic string containing special characters (< > or similar) directly as a text node child of IonLabel
2. Observe global ion-item padding/styles reset across entire app
3. Wrap the same string in a `` — issue disappears

### Code Reproduction URL

I cannot invest more time into this report unfortunately, else I would parse to identify the exact string that causes the issue.
Just happy to advise of our workaround.
