Bug: Katex messages are not rendered

[Abbas-Askari]

Description:

If the RC server has KaTeX enabled then KaTeX part of the messages are not rendered in Embedded. Messages appear differently in RC Main and Embedded due to this issue. See screenshots.

Steps to reproduce:

• Open Rocket.Chat's Embedded Chat.
• Connect to a host who has KaTeX Enabled and Allow Dollar Syntax switches enabled in the RC server settings.
• Send InLine KaTex: $You Cant See Me$ and Observer that You Cant See Me is not visible but first half is.
• Send $$You Cant See Me$$ and Observer that an empty message is rendered.

Expected behavior:

• Inline and Block KaTeX should render properly if KaTeX is enabled on the server.
