DynamicPageTitle flickers on scroll when heading wraps (snapped transition)

[knottykid]

Bug Description

When using ui5-dynamic-page with ui5-dynamic-page-title, the title flickers/jumps during the snap/expand transition if the heading wraps to multiple lines. This happens without any custom styling or shadow DOM overrides.

Affected Component

DynamicPageTitle

Expected Behaviour

Title remains stable; no visual jump/flicker during snap/expand.

Isolated Example

No response

Steps to Reproduce

1. Render a ui5-dynamic-page with a long heading in DynamicPageTitle so it wraps to 2+ lines.
2. Ensure the page has enough content to scroll.
3. Scroll up/down through the snap point (header transitions between expanded/snapped).
