Bad line breaking in markdown cells with a math symbol.

[eendebakpt]

Description

When a sentence ends with a math symbol and a dot, the line breaking in jupyter lab can separate the symbol and the dot.

Reproduce

1. Enter a markdown cell with text A markdown cell with a sentence ending in a symbol such as a Greek rho with a dot for which the line breaking ends up bad $\rho$.
2. Vary the width of the notebook untill the line breaks between the rho and dot.

Expected behavior

The line breaking algorithm should keep the rho and dot together.

Context

• Operating System and version: Windows
• Browser and version: Chrome
• JupyterLab version: 4.1.4

This may be a MathJax issue; we use MathJax to render LaTeX in Markdown. See also #14570, which is about explicit line breaks in LaTeX.
