我想我上周已经修复了这个问题：

> <https://github.com/discourse/discourse/pull/42303>
>
> Previously, the mobile composer swallowed pinch-zoom (and scroll) gestures becau…se \`editorTouchMove\` called \`preventDefault()\` on every touch gesture and .composer-fields/.submit-panel used \`touch-action: none\`.
> 
> This caused issues when the composer was zoomed in, it was nearly impossible to zoom back out, resulting in elements not being reachable. 
> 
> Meta \`t/408540\`
> 
> This change makes editorTouchMove ignore \*\*multi-touch gestures\*\* and switches those regions to touch-action: pinch-zoom, so the browser's native zoom works over the composer while accidental scroll-panning is still blocked.

所以也许你的论坛还没有更新这个更改？你是在这个提交之后更新的吗？
