Plan mode has become unreliable

### Describe the bug

The last couple of weeks planmode starts executing the plan randomly. Sometimes it waits for acceptance, as it is supposed to, but other times it asks me but continues straight away without waiting for answer. I don't see any pattern in it.

I'd expect Plan mode to always **_ONLY_** create a plan

### Affected version

1.0.57

### Steps to reproduce the behavior

Plan, execute, plan etc. The it will happen at somepoint

### Expected behavior

Plan mode always waits for accept before starting autoimplement

### Additional context

Awsome product by the way - thanks

該 issue 未指明任何檔案或測試。在版本 1.0.57 上重現 Plan/execute/plan 序列，並觀察執行是否會在接受之前繼續；完成的標準是，Plan mode 始終等待明確的接受後才開始自動實作，並包含一個涵蓋該行為的回歸測試。
