Incorrect capitalization of “YouTube” in aria‑label generated by LazyLoad

[worldwildweb]

Describe the bug

When LazyLoad → Enable for iframes and videos is enabled, WP Rocket replaces embedded YouTube iframes with a placeholder <button class="play"> element. The element’s aria-label attribute reads "Play Youtube video"—the lowercase t in Youtube violates the correct brand capitalization "YouTube". Automated accessibility testing tools (e.g., Silktide) flag this as an accessibility/spelling error.

To Reproduce

1. In WordPress admin, go to Settings ▸ WP Rocket ▸ Media.

2. Tick Enable for iframes and videos under LazyLoad.

3. Ensure a standard YouTube <iframe> is present in a post/page.

4. View the page on the front end.

5. Inspect the placeholder play button:

   <button class="play" aria-label="Play Youtube video" data-rocket-onclick="this.rocketonclick(event)"></button>
   

6. Note the lowercase “t” in “Youtube”.

Expected behavior

The aria‑label should use correct brand capitalization:

<button class="play" aria-label="Play YouTube video" data-rocket-onclick="this.rocketonclick(event)"></button>
