在Visual Studio代码中查找并替换

我在VSCode中编辑的文件中包含以下行：

...............111.........111.............111..

我想.用0s 替换所有。但是，当我突出显示行并为.s 查找/替换时，文档中的所有. s都会被替换，而不仅仅是我选择的行中的s，即使我切换“查找选择”按钮也是如此。这是一个错误吗？在其他编辑器中，如果我选择了一段文本然后执行查找/替换，则它将仅在所选块内查找/替换匹配项。

下面是一个片段，您应该可以重现该问题。该...............111.........111.............111..行在test_unicode函数内部。
