Usage of dropdowns are breaking HTML anchor #27408
Description
While working on the release 1.3.1, I found the following warning:
- doc/modules/grid_search.rst:611: WARNING: Failed to create a cross reference. A title or caption not found: 'pipeline_nested_parameters'
- sklearn/feature_extraction/text.py:docstring of sklearn.feature_extraction.text.CountVectorizer:59: WARNING: Failed to create a cross reference. A title or caption not found: 'stop_words'
- sklearn/feature_extraction/text.py:docstring of sklearn.feature_extraction.text.HashingVectorizer:86: WARNING: Failed to create a cross reference. A title or caption not found: 'stop_words'
- sklearn/feature_extraction/text.py:docstring of sklearn.feature_extraction.text.TfidfVectorizer:71: WARNING: Failed to create a cross reference. A title or caption not found: 'stop_words'
After investigation, those warnings a linked to the following pattern:
.. _anchor:
|details-start|
**Title**
|details-split|
Blabla
|details-end|
and when using
:ref:`anchor`
Sphinx failed to create the reference.
We need to investigate and to take into account this issue when reviewing the dropdown menu thingy.
