Chrome Debugger Source Files Out of Date

I find on occasion that my source files are out of date in the Chrome debugger. Sometimes I can tweak the source code and get it to rebuild and Chrome picks up the changes. Other times it requires restarting ionic serve.
I don’t think this is a problem with Chrome because I have the cache disabled, and even try to do a “Empty Cache and Hard Reload” (on the refresh button in the browser), but still the old files remain.

Has anyone seen this and have any tips to fix/prevent?

I’ve just discovered that if I hit Save in VSCode my files update. I shouldn’t have to do this since I have the autosave setting on, but I guess it’s not perfect.
