Description

The Typography size settings (S, M, L, XL, XXL) in the Cover block do not affect the text size as expected. Additionally, the Duotone filter does not apply correctly when selected, resulting in no visual changes or inconsistencies.

Expected Behavior
The text inside the Cover block should resize according to the selected typography settings.

The Duotone filter should properly apply to the image inside the Cover block.

Step-by-step reproduction instructions

Typography Issue:
Open a page or post in the WordPress block editor (Gutenberg).

Add a Cover block and insert an image or background color.

Add a text element (e.g., a Paragraph block) inside the Cover block.

Try changing the text size using the Typography settings (S, M, L, XL, XXL) from the sidebar.

Observe that the text size does not change despite selecting different sizes.

Duotone Issue:
Add an image inside the Cover block.

Go to the Filters section in the block settings sidebar.

Select any Duotone filter (e.g., black & white, sepia).

Observe that the filter does not apply or works inconsistently
