Hey there,

Am I the only one who have problem with master version?

Whenever I try to pinch zoom, the markers disappear and the map is frozen.

It happens to me on a Nexus S running 4.1.1 in webview, in stock browser and chrome browser.

Setting fadeAnimation and zoomAnimation to false doesn't change anything.

研究方向: Investigate the pinch zoom behavior in Leaflet's source code, specifically looking at the touch event handlers in `src/map/handler/Map.TouchZoom.js`. The issue mentions `L DISABLE 3D = true` which suggests a CSS 3D transform workaround. Check comments from users who may have posted workarounds or fixes. Reproduce the issue on an Android device with Android 4.1.1 using the stock browser, Chrome, and WebView. Look for any linked PRs or forks that address this freeze. The high comment count may contain valuable clues, so review them for potential solutions or root causes.
