!a || !b => !(a && b) i.e. original was equivalent to !(storedTheme === 'light' && storedTheme === 'dark') which would only be true for Erwin Schrodinger.

Thanks for opening this PR @battlesnake
IDK why it has finally not been included in #38626 since it was the original change, confirmed by my first tests in #38626 (comment). Maybe something forgotten while mixing both solutions :)

Thanks, I'm actually quite surprised that such an issue was actually found live already by someone! I just found it by analysis while translating the example to an AngularJS directive. |

Description
In the DOCS only:
I found an always-false condition while reading an example. It's for a branch that's difficult to test and will rarely get triggered (even on a global scale), so understandably hasn't been noticed yet.
Motivation & Context
In the DOCS only:
Example for color-modes / theme switcher will likely fail to handle changes in browser setting correctly, due to always-false conditional expression.
