Appears these aren't working on ex: https://build.webkit.org/results/GTK-Linux-64-bit-Release-Tests/r292391%20(6950)/results.html

I wiped out the associated change in results.html from https://bugs.webkit.org/show_bug.cgi?id=231544 when preparing it for a patch. Will add in this bug.

I can no longer open differences/expected/actual files for SVG files, if they fail.
Since this is the only code that touches the "output_filename" function in a while, it must be guilty for this.

Some context: if e.g. svg/W3C-SVG-1.1/animate-elem-02-t.svg fails, the generated results.html now contains links to "file:///Users/nzimmermann/Software/GitRepositories/WebKitVanilla/WebKitBuild/Release/layout-test-results/svg/W3C-SVG-1.1/animate-elem-02-t.svg-diffs.html"

The ".svg" is superfluous and thus the link points to nirvana now.

The JS code in LayoutTests/fast/harness/results.html implements the 'static testPrefix' method, which contains following check:

         else if (Utils.splitExtension(parts[0])[1].length > 5) {

Utils.splitExtension(parts[0]) returns "["svg/W3C-SVG-1", "1/shapes-rect-01-t"] in my case -- it treats the dot in the folder name as file extension.

The implementation of Utils.splitExtension() needs to be reworked:

    static splitExtension(testName)
    {
        let index = testName.lastIndexOf('.');
        if (index == -1) {
            return [testName, ''];
        }
        return [testName.substring(0, index), testName.substring(index + 1)];
    }

Ok, I'll revert it locally for now, so that I can proceed to do what I actually wanted :-) Feel free to proceed with a fix rather than a roll-out. I'm happy to cross check your patch.

This is hitting other folks as well, heard the question now two times already in Igaia, why results.html pages are broken.
