Preload Links handling .mp4

[worldwildweb]

Describe the bug
When the Preload Links option is enabled, hovering over a link containing .mp4 in the href causes a 404 error in the browser console.

Example error:

GET https://wpr.willychataigner.com/wp-content/uploads/2024/12/metaplan-5-jahre-1080p30f.mp4/ net::ERR_ABORTED 404 (Not Found)

Example HTML causing the issue:

<a class="" href="https://wpr.willychataigner.com/wp-content/uploads/2024/12/metaplan-5-jahre-1080p30f.mp4">link</a>

This behavior is also reproducible with .mp3 files and possibly other unsupported extensions.

To Reproduce
Steps to reproduce the behavior:

1. Enable the Preload Links module.
2. Add an <a> tag with an href pointing to an internal .mp4 file to a page or post.
3. Hover over the link.
4. Observe the 404 error in the browser console.

Expected behavior
Links pointing to unsupported file types (e.g., .mp4, .mp3) should be excluded from preloading, similar to how other file extensions are already excluded.

If applicable, provide screenshots showing the issue.

• The exclusion logic for file extensions in the Preload Links module can be found here:

  )
• Current exclusions include:

  $images_ext = 'jpg|jpeg|gif|png|tiff|bmp|webp|avif|pdf|doc|docx|xls|xlsx|php';

• .mp4 and other media files (e.g., .mp3) are not included in the list and should be considered for exclusion.
