Spinner: Drop dependency on jQuery Mousewheel

mgol · web-flow · commit 6843ced12e40 · 2025-03-18T11:45:00.000+01:00
1. Listen to the native `wheel` event without depending on any wrapper plugins. 2. Keep listening to the `mousewheel` event for compatibility with projects using the jQuery Mousewheel plugin but route it to the `wheel` handler. Closes jquerygh-2338
