The formula
$$\begin{align} \lim_{x \to 0} (\cos x)^{\cot x} & =\lim_{x \to 0} ((1+(\cos x-1))^{\frac{1}{\cos x -1}})^{(\cos x -1)\cot x}\\\\ … renders like this with the HTML-CSS or Common HTML renderers: 
My bug report is about the close parenthesis at the end of the exponent. It should be to the right of $\cos x -1$, not overlapping the $-1$.
This with Firefox 114.0.2 (64-bit), Mozilla Firefox Snap for Ubuntu, canonical-002 - 1.0.
