Hi,

I’ve found that Ark (24.12.3) won’t open [html/zip/png polyglot](https://gildas-lormeau.github.io/Polyglot-HTML-ZIP-PNG/SUMMARY.html) files (self-extracting archives) created by the browser extension [SingleFile](https://github.com/gildas-lormeau/SingleFile). Opening the files with a browser works as expected.  
They have the file extension `*.u.zip.html` and `*.zip.html`, and `file --mime-type FILE.u.zip.html` report it as `image/png`.

`$ unzip FILE.u.zip.html` works just fine, but Ark will throw an error: `No suitable plugin found. Ark doesn't seem to support this file type.`  
By renaming the `*.u.zip.html` to `*.u.zip`, Ark will find no issues opening it as an archive.

My question is then:  
Is there any way to make Ark see the `*.u.zip.html` as an archive without renaming the file?
