Steps to reproduce

Just like #8125/#7403, but happening on Chromium instead:

• Have a cheap-o USB mouse with a "clicky" scrollwheel
• Launch Linux+Chromium
• Go to any Leaflet map
• Use the scrollwheel to zoom in/out

Expected behavior

Zoom level changes by 1.

Current behavior

Zoom level changes by 2.

Environment

• Leaflet version: git checkout from main branch as of 2023-02-22 (1fa85b6)
• Browser (with version): Chromium 109.0.5414.119
• OS/Platform (with version): Debian bookwork/sid.

Screen is normal DPI (i.e. window.devicePixelRatio is 1).

At first sight this looks like a regression from #8298, and most probably will need the same diagnostics as #7403.

Chromium on Win+Mac needs to be checked for this.
