Chrome Developer Tools caches old version of JavaScript files

Chrome DevTools works fine for me. When I load it for a page it remembers beyond the lifespan of the chrome process what sources I have open; although it gets the order wrong. I see two differences in our devtools prefs: disable cache and enable maps. So I would advise:

1) uncheck disable cache (while DevTools is open), 2) (if 1 didn't work) press the "Restore defaults and reload" button.

The issue persists in 78.0.3904.97. To fix it run settings > advanced > reset.
