[BUG] math mode deletes above code block

[rwang2022]

Description

Typing in math mode (both inline and block) causes it to delete part of a code block above. It deletes everything after a >=.

To Reproduce

Put this in Obsidain

optional<double> safe_root(double x) {
    if (x >= 0) return optional<double>{sqrt(x)};
    else return optional<double>{};
}

Below it, try to do mk (which should expand into $$0$) and type anything.
