Can you explain what's the intention?

When developping a color theme extension, which I defined more than one color themes, vscode will always initialize with the first color themes provided by my color theme extension after reload browser(vscode in web), see the code blew:

I expected that vscode will initialize the color theme which is used before.

With the suggested code change it will still pick a theme from the extension under dev. But only if it provides a theme of the same type (dark, light....)
I don't think that makes things easier to understand...

Ah, but it defaults to the first.
Sure, why not.
