Resource Warning: unclosed file ... _sri.json while executing show(p)

when executing a show§ I get the following warning using the Pycharm IDE. Does anyone have any ideas on what is happening here? The plot executes fine.

\venv\lib\site-packages\bokeh\ ResourceWarning: unclosed file <_io.TextIOWrapper name=‘C:\…\venv\lib\site-packages\bokeh\_sri.json’ mode=‘r’ encoding=‘cp1252’>
_SRI_HASHES = json.load(open(join(ROOT_DIR, “_sri.json”)))

It’s a small resource leak, please file an issue on GitHub.
