嘿 @Ethsim2 我刚刚合并了一个修复此问题的补丁，很快就会可用。

> <https://github.com/discourse/discourse/pull/41711>
>
> PR #41366 introduced a regression on iOS where text-selection gestures in the co…mposer would get canceled. The scroll-lock added there routes composer touchmove events through body-scroll-lock, which calls \`preventDefault\` at scroll boundaries -- and a short textarea is always at its boundary -- so iOS never got a chance to handle the selection-handle drag.
> 
> Add a capture-phase touchmove listener on the editor that stops propagation when the editor has a selection, so the event never reaches body-scroll-lock's handlers and iOS handles the gesture natively.
