glow not rendering heading levels other than top-level

[Halfwalker]

Describe the bug glow does not seem to render headings other than top-level # Heading 1. Other levels like ## Heading 2 render in a color, but also show the ##

Setup

• OS : Ubuntu 20.04 and 22.04
• Shell : zsh and bash
• Terminal Emulator : alacritty, gnome-terminal, xterm (without Hack Nerd Font)
• Terminal Multiplexer : tmux and no tmux
• Locale : en_US.UTF-8

Source Code Simple test.md

# Heading 1

## Heading 2

### Heading 3

#### Heading 4

* list item
* another list item
    * sub-list item
    * and another

Normal text
*single asterisk*
**double asterisk**
_underscore_
__double underscore__

Expected behavior The sample test.md should render appropriately. # Heading 1 renders as expected, with coloring/bold/etc. ## Heading 2 and the others only render in blue and show the heading level hashes

This may well be an unintended and unexpected confluence of factors like font, terminal etc.
