feat: Math inline content

[matthewlipski]

Summary

This PR adds math inline content to alongside the math block. The UX is similar but differs in determining when the popup is open. The math block can contain the text cursor and still have the popup closed, requiring an Enter keypress to toggle and Escape to dismiss. The inline math keeps the popup open while the text cursor is within in.

Rationale

It makes sense to ship both a math block and inline content together, as they are often used together and fulfil slightly different use-cases.
