ui.input demo page broken

Description

At first I thought it was something on my end but I think this is legitimate. On https://nicegui.io/documentation/input you will notice only the first demo populates correctly. I tried it locally and got the same behaviour with these errors in the console. Other demos might also be affected, I didn't check all of them.

It appears to be caused from this commit:

As I just commented on #1617, it is so good you spotted this issue, @natankeddem!
And I agree that f253d9f ultimately caused the bug.
