fix #3201

  • First time rendering does not need to look for elements from child nodes
    ** Avoid unnecessary checks with node.pP.
  • Sibling elements are always searched, so there is no need for a for loop.
    ** Need only findInsertBefore(node.vC[0])

I have not added any additional tests as there is already sufficient testing on the expected rendering results.

For performance, although it is a simple test, I have added a test to check that I am not getting as much computation as n to the nth power.

The author should do the following, if applicable

  • Add tests
  • Run tests
  • bun run format:fix && bun run lint:fix to format the code

* First time rendering does not need to look for elements from child nodes
** Avoid unnecessary checks with `node.pP`.
* Sibling elements are always searched, so there is no need for a for loop.
** Need only `findInsertBefore(node.vC[0])`
