What is the current behavior?

Issue Number: #1296 #1623 #1562 #1541

On macOS and Linux, the Text Comparer shows both panes but never renders any +/- highlighting. Monaco editor computes diffs in a web worker, and labels that worker with a URL fragment:

app://localhost/.../vs/base/worker/workerMain.js#editorWorkerService

macOS (WKWebView) and Linux (WebKitGTK) are both WebKit, and WebKit passes the fragment to the custom scheme handler. Both platforms carried the same RemovePossibleQueryString, which cut the URL at ? but not at #, so the file lookup missed and the worker received Blazor's placeholder text as its script:

SyntaxError: Unexpected identifier 'is'

No worker means no diff computation, so no decorations. Windows is unaffected because WebView2 is Chromium and doesn't pass the fragment to its resource handler.

What is the new behavior?

Build	Worker request	Text Comparer
before	125 bytes, There is no content at …	no highlighting
after the fix	309 809 bytes of worker source	highlighting

Verified on macOS 26.5 arm64 and Ubuntu 26.04.
