-// Workaround for browser-specific bugs when copying code snippets.
-//
-// * In Firefox, copying text that includes elements with `user-select: none`
-//   inserts extra blank lines.
-//   - Firefox issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1273836
-//   - Rust issue: https://github.com/rust-lang/rust/issues/141464
-//
-// * In Chromium-based browsers, `document.getSelection()` includes elements
-//   with `user-select: none`, causing unwanted line numbers to be copied.
