Description swulf 2023-07-04 01:28:35 UTC

Description:
A formula entered in Writer cannot correctly render something raised to multiple powers (i.e. 'a squared, cubed'. Instead, it simply concatenates the two powers, resulting in 'a to the 23'.

Steps to Reproduce:
1. Open a Writer document
2. Insert a Formula object
3. For example, enter '{a^2}^4'
4. Writer displays 'a^24'

Actual Results:
Writer displays 'a^24'.

Expected Results:
Writer should display a-squared raised to the 4th power.


Reproducible: Always

Simply enter expression functionally in StarMath with Parentheses () as 
"(a^{2})^{4}"

What else could the markup be, IMHO explicitly requiring the parenthesis to establish the ODF node is NAB.

You are quite right. I realized this after submitting the report(!) but I couldn't see a way to delete it.
