Description

Current Behavior

In Node-RED v3.1.3 using node-red-dashboard 3.6.2, it’s apparently not possible to drag/reposition nodes around using the latest Brave Browser (on Mac; v1.61.114 Chromium: 210.0.6099.199). Brave's "shields" are down. I tried clearing cache. No interesting errors in console when trying to select/drag.

Doing the same thing from the same server using Safari works as expected.

Research direction
Investigate the drag and drop implementation in the dashboard. Look at the JavaScript event handling for mouse/pointer events, as Chromium may handle them differently. Check for any CSS that might interfere with pointer events (e.g., user select, touch action). Test with Brave's shields down and in incognito mode. Consider using Pointer Events API instead of Mouse Events. Look at files like ui.js or drag.js in the repository.
