Math Click-to-Edit Test

✅ New Features Implemented!

Click on any rendered math equation to convert it back to editable LaTeX
Original LaTeX is preserved in data-latex attribute
Works with both inline ($...$) and display mode ($$...$$) equations
Cursor is automatically positioned for easy editing
Auto-converts back to rendered math when you finish typing

Test 1: Click-to-Edit Basic Math

Click on any of the rendered math equations below to convert them back to editable LaTeX!

How to test:

Look at the rendered math equations below (they appear as nicely formatted math)
Click directly on any math equation
The equation will instantly convert back to its LaTeX source (e.g., $E = mc^2$)
You can now edit the LaTeX directly!
When you type the closing $, it will render again automatically

Expected behavior: Clicking on math converts it to editable LaTeX text.

Test 2: Click-to-Edit Display Mode Math

Display mode equations ($$...$$) also support click-to-edit!

Test display mode:

Click on any display mode equation (the larger, centered ones)
It will convert to $$...$$ format
Edit and re-type the closing $$ to render again

Test 3: Edit Multiple Equations

Test editing multiple equations in a paragraph.

Workflow test:

Click on the first math equation to edit it
Modify the LaTeX and close with $
Click on another equation to edit that one
All equations work independently!

Test 4: Complex LaTeX Expressions

Test with complex mathematical expressions.

Complex expressions:

Fractions, integrals, summations all work
Click any complex equation to see its LaTeX source
The full LaTeX is preserved perfectly

Test 5: Insert New Math via Toolbar

You can still insert math using the toolbar, and it will also be editable!

Toolbar insertion:

Click the "TeX" button in the toolbar
Enter a LaTeX expression (e.g., x^2 + y^2 = r^2)
The math will render
Click on it to edit it again!
