### Problem Description

While indexing documents with dynamically added fields, if multiple of those fields are objects are are deeper than 3-5 objects, performance is degraded significantly.

This bug was introduced in: https://github.com/elastic/elasticsearch/pull/90674

### Steps to Reproduce

I built a micro-benchmark to replicate this particular bug. 

But, any dynamic object parsing will cause this.

To mitigate the issue, statically mapped fields for objects is required. 

### Logs (if relevant)

Attached are two JFR files indicating the difference between when the bug was introduce vs. not.
