This looks ok here. But I'm a bit confused by the logic of the previous line.
According to https://github.com/iheyunfei/vite/blob/a7a9a361cf13670c2e241620ddaf15021eda26b5/packages/vite/src/node/config.ts#L103, the inline config mode should be the one winning over the config file mode, and that is not the case here AFAICS. @AlexandreBonaventure I think you were using this feature, does it works correctly for you when overriding --mode in the CLI? It should win over the one you used in your config file.

@iheyunfei as a note, it would be good to have an issue for this kind of PR with a reproduction for reference. It is easier to merge PRs when we have a clear bug that they are fixing.

@patak-js Yes, I'm going to raise an issue. For your question, I look down the codes and It won't win over the mode in the config file.

Fix it too. After looking back, I found I just solve inconstancy in some cases. Still, there is a case that could not be easily fixed. I will open another issue to describe it.
