Rich text editor: Code blocks and math use a serif font by default

[personalizedrefrigerator]

Operating system

Windows

Joplin version

3.0.0

Desktop version info

Joplin 3.0.0 (dev, linux)

Client ID: 44da07c87ebf4662aa0e0f97f77f7f38
Sync Version: 3
Profile Version: 46
Keychain Supported: No

Revision: a40c3b7

Backup: 1.4.0

Current behaviour

1. Open the markdown editor -- add a math expression with a "≠" symbol (e.g. $3 \neq 4$) and a code block.
2. Switch to the rich text editor.

Currently,

1. the ≠ symbol is rendered incorrectly, and
2. the code block is rendered in a serif font.

Screenshot:

Expected behaviour

The code block should render in a monospace font and the rendered KaTeX should use the KaTeX fonts.
