bug/Partition_html Function Fails to Extract Accordion Titles

[honeylane]

Describe the bug
The partition_html function fails to extract accordion titles. For example, when applied to the following FAQ page:
Phonak FAQ, the extracted elements do not include the questions.

To Reproduce
from unstructured.partition.html import partition_html

url = "https://www.phonak.com/en-int/support-options/frequently-asked-questions"
elements = partition_html(url=url)

for el in elements:
print(el.to_dict())

Expected behavior
The extracted elements should include the FAQ questions as titles.
For example, a question like:
"Which Bluetooth profiles are required to support my Phonak hearing aids?"
should appear in the parsed output as a title element.
