Tabsize in settings.json not activated after saving new python file

Description of the problem or steps to reproduce

After start Micro, open a new buffer/tab, type some Python-code, and for code-highlighting saving the Python py-file.
But after saving this new py-file it does not activate the tabsize:4 in my settings.json:

{
    "*.py": {
        "tabsize": 4
    },
    "eofnewline": false,
    "filemanager.openonstart": false,
    "hlsearch": true,
    "scrollbar": true,
    "softwrap": true,
    "tabsize": 2,
    "wordwrap": true
}

When closing Micro, restart and open a py-file then the tabsize (4) works well.

Is this an issue or is there a way when start a new py-file in Micro and after saving this new py-file (without restart Micro) the tabsize is set to 4?

PS: the default tabsize is set to 2

Reproduce the behavior in Micro 2.0.13 using a new unsaved Python buffer and the shown settings.json, then save it as a .py file. Trace how settings are applied on save versus startup; done means the Python-specific tabsize of 4 takes effect immediately without restarting Micro.
