As noted in topic, for some reason I get different code highlighting in different modes:

Live preview mode:

Read mode:

What I did try:

• Turn off community plugins with restricted mode
• Turn off all css snippets I have
• Reload the app :)

OS: Ubuntu 22.04

The markdown written is exactly:

my_set = {'a', 'b', 'c'}
my_dict = dict.fromkeys(my_set, 0)
print(list(my_dict.keys()))  # Order is not guaranteed; e.g., ['b', 'c', 'a']

I believe the issue might not be related to the theme itself, but maybe someone else had this issue and fixed it somehow.
