在Chrome开发人员工具中停用自动保存CSS更改

我指的是Chrome开发工具的来源面板中的保存功能。我在Chrome的稳定版本中使用了这个功能很久，但是从开发者渠道安装构建版本后，我注意到一旦我第一次保存文件，Chrome就不再提示我保存并且只是做它会在每次更改后自动完成。

I am referring to the save feature in the 'Sources' panel of the Chrome Dev Tools. I have been using this feature for a long time in the stable release of Chrome, but after installing the build from the developer channel, I notice that once I have saved the file the first time, Chrome no longer prompts me to save and just does it automatically after every change I make.

这非常痛苦，因为我在开发工具中进行了大量实验性更改，而在调试时我不想保存，我希望Chrome只在我明确告诉它时保存文件。

This is quite a pain, as I make a lot of changes experimentally in the dev tools whilst debugging which I don't wish to save, I would like Chrome to save the file only when I explicitly tell it to.

有谁知道是否有办法禁用这种自动CSS保存功能？

Does anyone know if there is a way to disable this automatic CSS saving?

（抱歉没有屏幕截图，当我在上下文菜单中时，我的PrtScn键似乎无法操作）

(Apologies for no screenshot, my PrtScn key seemingly won't operate when I am in a context menu)

更新：

我已回复到目前的稳定版本27.0.1453.93，并且行为似乎相同。

I have reverted to the current stable build, 27.0.1453.93, and the behaviour appears to be the same.
