DPI mouse interaction scaling problem on web

[frnsys]

Describe the bug

When using the Chrome dev tools responsive tool I noticed that for DPRs 2 and 3 the graphics scale correctly but not the mouse interaction. I'm not certain if this is an issue with egui itself or with the Chrome dev tools.

To Reproduce
Steps to reproduce the behavior:

1. Load https://www.egui.rs/#demo in the latest version of Chrome (Google Chrome 143.0.7499.40)
2. Open the dev tools and the responsive tool
3. Set the DPR to 2 or 3
4. Reload the page

Expected behavior
Mouse interaction should scale along with the graphics
