MathML tags (mfrac) parsing issue

[ksarathkumar]

Question: Are you using the latest version of flutter_tex package?
Answer: yes.

Question: If you are looking for a feature, have you watched the Demo Video and gone through the examples folder?
Answer: yes

"mfrac" MathML tags are not being parsed and displayed as plain text instead of (numerator)/(denominator).

Sample MathML.

Output: If x = a ( 2 θ − s i n 2 θ ) and y = a ( 1 − c o s 2 θ ) , find d y d x when θ = π 3 .
Expected output: If x = a ( 2 θ − s i n 2 θ ) and y = a ( 1 − c o s 2 θ ) , find d y/d x when θ = π/3 .
