Expected behavior

Promp by linter warning of the error of the mismatched bracket

Steps to reproduce the behavior

This snippet broke the server:

`
Diameter \\( d \\) of a circle given area \\( A \\) can by obtained via \\(d=\sqrt{\frac{4A}{\pi}}\\)
`
Will show as: Diameter \\( d \\)
of a circle given area \\( A \\) can by obtained via \\(d=\sqrt{\frac{4A}{\pi}}\\)
