Summary by Sourcery

Bug Fixes:

Fixes a BuildException that occurs when importing LaTeX equations containing raw \\ line breaks from external sources (e.g., Notion). This fix introduces a preprocessing step that wraps such input in an aligned environment, preventing CrNode exceptions without modifying the math rendering library.
Related to #7949

Summary by Sourcery

Prevent BuildException when rendering LaTeX equations containing raw '\' by wrapping them in an 'aligned' environment using a new preprocessing step.

Bug Fixes:

Prevent BuildException when importing LaTeX formulas with raw '\' line breaks by wrapping them in an 'aligned' environment if not already wrapped.

Enhancements:

Introduce a _safeLatex preprocessing function to wrap raw line breaks in an aligned environment before rendering.
