fix: set proper default value in radix with content block (#4937)

User reported in discord.

Radix components like accordion does not open first item by default when
use with content block. The reason was in our default detection.

We used indexes within ancestor and when put item inside of content
block template it gets 0 but not rendered.

Here improved the logic to reset index when render inside of block
template.
