## Summary
Fixes the initial enabled/disabled state of chat variable checkboxes by
correcting a helper function that previously always returned .
## Problem
in had two statements:
Because of the early , the function always returned , so all chat
variable checkboxes were initially disabled regardless of the field.
This also made the helper inconsistent with , which enables all fields
by default except .
## Fix
Update to use the same condition as :
This ensures:
- All chat variable checkboxes are enabled by default
- remains the only field disabled by default
- Behavior is consistent between the helper and the checkbox map
initialization in .
No API or backend changes are involved; this is a small, isolated
frontend bugfix.
### What problem does this PR solve?
- Use negative lookbehind (?<![a-zA-Z]) so \] and \) inside commands
(e.g. \right], \big)) are not treated as block/inline delimiters
- Use greedy matching to capture up to the last valid delimiter, fixing
truncated formulas (e.g. C_{seq}(y|x) = \frac{1}{|y|} ...)
- Add unit tests for preprocessLaTeX
